Or are they restored? And if so...am I right? :scratch2: Sandy G 09-03-2012, 08:50 PM This all YOUR stuff ? If so, you've got a HELLUVA collection ! radiotron 09-03-2012, 08:55 PM The RCA should make the nicest pic restored, followed by the Crosley. Or are they restored? And if so...am I right? :scratch2: Sadly the crosly is getting junked out next week if you want it its free the doors knobs and pencilbox door are gone, and it has bad caps. The rca was sold last month. tThe zenith floor model radio I have the tabletop to. radiotron 09-03-2012, 08:59 PM This all YOUR stuff ? If so, you've got a HELLUVA collection ! a couple were a friends i also have a rare philco predicta aka my avitar. I have a 1951 admiral tabletop tv that works with a built in radio. DavGoodlin 09-04-2012, 09:53 AM That 1960 GE is an interesting one also. Is it a power-tuning and possibly remote model? They advertised how those shallow-depth models did not "protrude" into your living room. Cadman 09-04-2012, 10:19 AM What is the blonde model in your last pic? The one with the "square framed" round tube and hidden controls. Don't think I've seen one like that before... -Cory Einar72 09-04-2012, 10:23 AM What a motherlode! I'm glad you posted that 41 or 42 Zenith console. I have been looking for the rare AM-only version of that one, now everyone can see what I'm talking about.

David Roper 09-04-2012, 03:15 PM That's what I was wondering, but I think you mean the Crosley. I hate to see that happen to such a nice looking set...but I have a few nice looking sets that need a good tube. I'd very much like to know the condition of that one. radiotron 09-04-2012, 03:19 PM What was wrong enough on the admiral to cause it to get junked? Thats a crosley its not junked yet only about 1/3 done tubes are gone transformer, and caps are bad picture tube (I THINK) has shorts Trust me im not an idiot that goes and junkes everything he sees FISHTANK TVS ARE MY NIGHTMARE! radiotron 09-04-2012, 03:36 PM That's what I was wondering, but I think you mean the Crosley.

But if you are watching a DVD they show on top because of the anti copy protection that is encoded into the DVD. The lines then will come and go like every 30 seconds. Also, if the CRT has a short it can cause retrace. what are you using for a source on this set?

If not, do that. If it's fine, recap the set if it's all original. It would be best to change all the wax/paper caps at this point. Do it one at a time, don't cut 'em all out at once or anything. Check the resistors in the vertical circuit too. They tend to drift upward in value as they age. bandersen 09-12-2012, 03:52 PM Visible retrace lines are normal for an Admiral from the era. You can make a minor circuit modification to suppress them though. mbear2k was kind enough to scan and make available the details in Rider TV Manufacturers' Receiver Trouble Cures - Volume 1 http://www.oldtubes.net/library/free_manuals/ radiotron 09-12-2012, 07:33 PM Visible retrace lines are normal for an Admiral from the era.

It's only two threads down, from this one, right now. I'm sure anyone that had an interest has already read it. Why bring it up again? yes it was closed at my request, becouse the thread didnt have a word about the set just fighting about why i think you should use parts untill they die lnx64 09-23-2012, 08:44 PM I gotta say. You just joined this month and you already have 162 posts? Dayum. ggregg 09-23-2012, 08:45 PM That's it man, run em until they blow. There was no fight. There were a few members trying unsuccessfully to convince young Radiotron to follow a different path on his projects. He feels otherwise. AiboPet 09-23-2012, 09:04 PM NO!.....You don't "use the parts until they die" on a TV set. The "dead part" if left unnatended will almost ALWAYS bring the set out of safety tolerances....and then bring down the rest of the parts your "weak" part supports. Yes...you can usually "adjust out" the problem up until you notice the vertical size is "maxed" to one side or something...but it means you have something to tend to BEFORE you suddenly have NO vertical and the set becomes a basket case. Your signature pic shows you tend to just "tolerate" every show looking like you are watching The Coneheads (You are probly too young to know who those guys are.....Look 'em up, they are funny as HELL!). That linearity/height problem is something you HAVE to diagnose. At least get a decent pattern generator so you can SEE there is a problem before it becomes much worse. Even just a good clean crosshatch can be a WONDERFUL tool. N2IXK 09-23-2012, 09:05 PM yes it was closed at my request, becouse the thread didnt have a word about the set just fighting about why i think you should use parts untill they die The problem with your "philosophy" is that some components can take other, often irreplaceable components out when they fail. A filter capacitor that fails shorted can take out a power transformer. A failed component in a horizontal oscillator circuit can burn up a flyback. A failed 10 cent part can potentially cause enough damage to prevent a set from ever running again. Certain types of components are KNOWN not to age well, and should generally be replaced (or at least PROPERLY tested) before applying power to an old set. If you know enough about vintage electronics and have all the proper equipment, you might get away with a CONTROLLED reduced voltage power-up stage-by-stage on some sets. But your posts tend to indicate that your skill set isn't there yet. jr_tech 09-23-2012, 09:12 PM I think Matthew Henry said it best: "There are none so deaf as those that will not hear" Good advice has been given here, and largely ignored or disputed. jr zenithfan1 09-23-2012, 09:30 PM I like to kinda let things just roll as they will but,........I'm getting a bit tired of it now. Radiotron or Johnny, why do you not listen to the experts? Why do you argue with them? I remember being very young and I listened carefully to what people like the ones here say. I STILL do at age 30. I try to learn something new everyday. We are trying to teach you what to, and not to do. When we say the caps are bad (even if the set works) they are bad. People here have tried to tell you exactly what is wrong with every set you have posted about. I know you say complain to tvtimeisfun but he really hasn't had much to say in general on the forums. You are the one posting a lot of things and should be responsible for your own actions. I really hope you are learning from your grandpa as to repair old sets. My grandpa died before I really got to know him and he was a tv repairman in the '60's and 70's. If yours knows his stuff on old electronics, learn everything you can from him and treasure the information, and also from the wonderful members here. Most of the people here worked on this stuff back in the day and still do so it's best to just listen to their advise. MOST importantly, do not get hurt on an old tv. These things have deadly voltage inside and we are trying to keep you safe as well. When things short out LIKE OLD ELECTROLYTIC CAPS they can put line voltages on the chassis at times amongst other hazards involved in old tv repair. Some sets have one side of the ac line on the chassis at all times and are dangerous to begin with so it's best to listen. I'm done rambling now and I guess it's my job as a moderator to do so once in a while but please think about it....K?...... lnx64 09-23-2012, 09:32 PM If it wasn't for the people here and their advice on how to fix things or identify things, my Samsung TV would have been back in the trash. But because we have smart people here, like radiotvnut that knew about the flyback issue well before I even turned on this TV set, I knew what to look for when it had problems right on day 2.. Boobtubeman 09-24-2012, 12:27 AM DANGER WILL ROBINSON DANGER!!! i sense a capacitor debate spillover from a closed discussion :boxing: josephdaniel 09-24-2012, 12:47 AM Here is a good idea next time you see a tv set or radio just skip over it and buy some test equipment like tube tester and capacitor checkers that should help you out a lot and show you wich caps really need replaced. if you really ate wanting to keep as many orgional parts in the tv as possible while keeping it working reasonably well this is the way to go for you I believe. Me I always replace the lyrics and papers in the old sets unless I don't have the part on hand. radiotron 09-24-2012, 08:53 AM Here is a good idea next time you see a tv set or radio just skip over it and buy some test equipment like tube tester and capacitor checkers that should help you out a lot and show you wich caps really need replaced. if you really ate wanting to keep as many orgional parts in the tv as possible while keeping it working reasonably well this is the way to go for you I believe. Me I always replace the lyrics and papers in the old sets unless I don't have the part on hand. i have a tube tester the cap thing is just my grandpa doesnt like giving out parts when the set works im not going against you guys its just that tvtimeisfun does the same thing he fired up a 65 zenith color that wasnt fired in over 40 years it only needed a horiz. output tube ive never a a set go with bad caps when i used it ive had tubes go out when i was watching it, but never caps in the 2 years ive been doing this lnx64 09-24-2012, 09:52 AM That's just stupid.. Capacitors go out more than tubes.. Tubes are in a vacuum.. Capacitors aren't and they DRY up! 2 years you've been doing this, and you're already this stubborn? Good luck with frying nice old TV's. Just because someone else does it, doesn't mean it's right. snelson903 09-24-2012, 10:43 AM capacitors are the number one thing in new or esp. old equitment that fail ,they can become leaky ,shorted,open,change value,become resisted ,they can cause intermitent problems, can cause unfiltered voltage's or in blocking aplacation's to damage semiconductor's or electron tube's . the old can type multi side electrolytic dry up ,are internaly leaky ,most of the time they are in a open condition. the same with the wax paper caps they failed back in day on regular base's heat & wax dont mix , im not a fan of reforming either if its bad replace it ,to say you have never had to replace a cap before or your grandpa doesnt like giving out parts when the set works ,is kinda a mystery. lnx64 09-24-2012, 10:49 AM I'm going to say this. This picture says it all.

So, REPLACE THOSE CAPS! good picture AiboPet 09-24-2012, 07:55 PM GREAT pic of "look for any that look swolen...or are sitting oddly on the board" I had posted in another thread about a generic 5" set (forget where I posted that). Your pic is a GREAT example of pretty much BOTH of those conditions. It's too bad only really these type of electrolytics do this very obvious fail. The rest....I am sorta having to GUESS..since I do not yet have a capacitor checker. Is an "ESR" meter really even sufficient to test the "big" caps? I ask...because I have seen that in order to check a cap correctly, you have to be able to CHARGE it to it's rated voltage. No way the little ESR meters I see with (I assume a 9V battery) can do this? I would get one for pretty much MOST the little solid state stuff I play with...but it seems not sufficient to have even a "good" meter with a capacitor checking section on the dial. Unless of course...I am wrong. Most the little "micro" sets I work with have electrolytics (just like these in most cases)...rated to maybe 16v-50v or so. Only place I have been running into "big boy" caps...are the big old Sony solid state sets ("big" being relative....since my "big" sets are 9" sets). The Sony sets with these bigger caps almost ALWAYS exhibit linearity and horizontal stability problems. I tend to recap them in a "shotgun" fashion without being able to really check 'em. wa2ise 09-24-2012, 09:12 PM Seriously, you need to replace the old electrolytic caps. They cost a lot less, and are easier to obtain than, a power transformer. Even the big multisection cap cans. You can use individual single unit caps to replace them. But don't just solder the new caps across the old caps, that won't protect you if the old caps short out (this is the failure mode to fear, this is what will ruin the power transformer). I've taken a hacksaw and cut the old can cap just above the crimp bulge (this is where the rubber gasket seal is housed), removing the old cap can and guts, and Ive drilled small holes thru the gasket and passed new cap leads from above to the terminals below. Some people will go to the trouble of carefully tucking the new caps inside the old can (after the guts are pulled out (nothing overly toxic, but don't eat it and wash your hands afterwards)) but I've just had the new caps out in the open (but take care to be sure they can't flop around and short out to something). Flybacks and yokes and CRTs are also hard to find replacements for, so we also change out the caps around them as well. I know, as a kid you probably have no real money to get this stuff, but you risk ruining hard to obtain parts. Tubejunke 09-28-2012, 01:46 AM Is an "ESR" meter really even sufficient to test the "big" caps? I ask...because I have seen that in order to check a cap correctly, you have to be able to CHARGE it to it's rated voltage. No way the little ESR meters I see with (I assume a 9V battery) can do this? As a technician I wish that I could answer this question and would like to know myself what difference there is (if any) between an ESR meter and the capacitance mode of common DVOMs. There is no use to go buy an ESR if you can use your digital meter I would think. Even in college we had an ESR and nothing more, but I know that there is a tester that actually loads the capacitor. That is what I would think that any of us would want, especially since we are dealing with working voltages way above those found in modern equipment. peverett 09-30-2012, 09:10 PM I agree with wa2ise, replace all electrolytic and paper caps. A while back, I restored a 1953 Emerson. There was one paper cap that was hard to get to. As it only had 4 volts across it(in the AGC circuit), I left it in. Guess what the cap failed in very short order, causing picture and sync overload. I had to go back in and replace it. A more recent experience was with a 1958 RCA portable. In this case, there were some capacitors that were packaged like the modern orange drops, so I assumed they were still ok. No! I had to replace these to get correct vertical linearity and height(which would shrink as the set warmed up). I am not sure if they were paper inside or just heat damaged. Now I just replace these as well! 40 to 50 year old caps are no good. The technology to make good, long lasting capacitors was just not available then. (I am not sure it is available now for electrolytics!). lnx64 09-30-2012, 09:21 PM (I am not sure it is available now for electrolytics!). Nope.. It just doesn't exist sadly.. Maybe longer than then, but not good. |
