So this had all its cords ripped out and was just seconds away from being tossed into the dumpster. When the lady told them don't lets put it on the floor....got it for 19.99$ she was ecstatic that I bought it :D

I can find nothing on this set, I see the earlier roundies and I see a few sets like mine but nothing identical, can't find any schematics, manuals, ads...notta...

So don't be scared, it is french Provencal. :D Yes not my favorite style....but you gotta admit it grows on you, if it was a 8foot console...in this style...nope...no way!!

I really don't want to power it on till I buy another variaic(had house fire, lost everything :tears:)but I do have a tube tester. The lady said, that another person did turn it on..I was like ekkk...

Might pop it open here in a minute and do a visual...

So thought? Worthy of a project? Hide it in a deep dark corner of the crawl space? :P

pretty sure its this chassis

nice all tube should be easy to get going. when you said all the cords ripped out I presume you just mean the power cord, not the yoke or CRT connections.

a Good start is to check the condition of the CRT before investing a lot of time and money.

late 60s model.decent sets with very ornate cabinetry.produce nice pictures when right

Well opened it up, it is cleaner then I expected. Didn't see any visually bad tubes.

That does look like the chassis! Looks like some repair man or last owner maybe? ripped the tube chart off the side of the cabinet and the chassis number tag!! Least they left the model tag.

looks like an instant on power trans on top of the regular trans. Hope the CRT is ok. The one in the set from the video tested like new, but I don't recall if it had the instant on.

That is all of the model tag. The chassis number is on a tag usually on the rear of the chassis. It will begin with T-XXX

I had a very kind great Aunt/Uncle who had that kind of furniture (and the same TV). I am sad when people say hurtful things those who chose this kind of furniture (although I know that hasn't been done here...yet). Personally I think it's pretty cool. Obviously of another era, but aint that the point?

Good luck fixing it.:thmbsp:

DaveWM

there is a good chance it will work just fine as is (most likely the only issue will be dirty pots). that era had pretty good caps in it, including the cans.

If it was mine I would pull the horz out and the vert out tubes, variac it slowly monitor the B+ to see if it comes up, and check to see if the cans get warm, I generally do this over a period of time (hours) to give the cans a chance to reform.

Stop at about 80vac input, there is no load on the B+ with the sweep tubes out.



Pulling the tubes mentioned is done since they are osc tubes and may not like the low power. If all goes well I put the tubes back in, hook up a current meter to the horz out cathode, and a HV prob to the anode and do a full power start, keeping an eye on both the horz out current and the HV. Look for horz current to be around 200ma and the HV not to go over 25kv. If either go too high I shut down and look for problems before trying again.

often wiggling tubes will correct problems, so that should be tried 1st depending on the faults that show up (in case the above startup does not result in a working set). beyond that you have to apply regular diagnosis skills.

I'll take a look again, but it looked like it was a two part tag and only the words chassis # is left.

Thanks for that! It would be nice if it just powered up with out any issues, not really normal for me :P Its a good thing I bought a huge can of dexoit....so many post and connectors on this thing.

If anyone could supply a sams for it, that would be awesome, I have lightly dabbled in tvs...and never found it really exciting...so it would nice to have some sort of guide on where to probe and the values. This thing looks to have a lot going on inside..

Maggy was notorious for using different chassis in the same
model so you gotta watch it ordering manuals. We only
used chassis #'s, the model is only safe for cabinet parts.
Tag is small maybe 1" by 1/2" usually green or white.
usually right on back of chassis but can be found other places
so look everywhere. If you dont find it & need a manual post
some chassis pictures & tube line-up & prob can find one
very close...

This is identical (99%) to my Magnavox U-911 chassis from '67 which was lost in hurricane Sandy. It makes a great pic. Be sure to 'dip' the cathode current on the 6JE6

10-12-2014, 03:04 PM
I think its a nice looking set, and I like the cabinet a lot. It's got character.....

I sure would like to see pictures of it once you are done with it.....

Did it come with a back....? 23" tube right.... What number...?

.

jfrog1983
10-12-2014, 03:23 PM
I will go try and do a 360 on the chassis and see if I can find the number somewhere else besides the tag.

Sorry you lost yours in Sandy, I lost my entire collection in a fire...

Well here are the two numbers on the rear of the chassis, you can see how I think the chassis # is missing..

I can't even imagine that. :( On the upside though, this looks like a very nice set for a fresh start. Not too common.

I think you found it. That "92010" #. It is either a T920 or a U920 I would say T920-10

Sams #887-2

Bill R
10-12-2014, 08:04 PM
T-920-10 would be my guess. The U numbers were usually used on the round tube chassis.

My "U" chassis was certainly rectangular..not 1 doubt in my mind.

Though I did stumble on to a magna-color owners manual....lets hope I get the write one...well time to wait another week :(

That's the one control I wish my RCA had!

I like this TV, if it were presented to me, I would get it right away. Very nice find!

jfrog1983
10-20-2014, 06:39 PM
Well the seller said, that they didn't log the 887 in...so they told me to keep these and issued a refund...so sucks for me, no sams...it was the only one I could find listed for sale....guess maybe I will be paying for a copy....grrrrrrr

The SAMS website costs a bit more but gives instant gratification, you can get it digitally within 24 hours. If you assign some value to your time it's really not a bad deal at all considering what a great service
They provide.

zeno
10-21-2014, 06:44 AM
Do a search for used Sams, you will find a lot that sell them
for 5-10 each. Be sure its a first gen NOT a copy. I dont
know what Sams sends now but I would be very careful
with PDF's etc, they can really suck.

I got one bad PDF from SAMS and they replaced it with a paper copy
For free - other couple have been great. One thing I like about digital copies is I never lose them.

Looks like my T-933. The thing on top of the power transformer is a power supply choke. The tuners can be finick as well as the horizontal blanking tube. If the picture is dark, change that tube first!
Of all my color sets, it has the best "dip" in horizontal tube current.

I know, the thrift store tossed a 600$ counter top microwave/convectional oven combo...I just couldn't say no, it has a bad leaf switch somewhere...there are only like 20..

Projects always cost money, and I am in the waiting stage of disability...so my only income is what I can squeeze off ebay, use to make 70k a year on ebay...then I lost me inventory to fire...moved out here into the middle of no where and can maybe get 400-800 a month :tears:

I have this book and it helped me with alot of tubed Mags, BUT a pull-out schematic for a T920 is not included, only a T904 - the first rectangular CRT Magna-color.
My fits on these sets always were CRT and video output related. The sound quality on these Mags was 2nd to none!

Send me a pm with your email and I'll scan you the applicable sections.

I have this book, but, mine does not have a T920 schematic. It does have the series 31,37,41,and 45 schematics. These are for roundies. Mine does not say vol. one so it is an older printing. They are a good resource.

I have an old clothes dryer in my bedroom with all my electronic stuff. I had an old microwave/convection oven sitting in the corner for months, also a thrift store find. It's in the kitchen now.

Yup, I'm in a similar financial boat, doing all I can to finally get on my feet. I have a few projects and have been gathering repair supplies as finances permit.
