I just picked up my first old TV to restore. I worked on TVs some years ago but just recently I wanted to get a older one. It is a Philco 49-1002. I usually deal with tube radios but I got the urge for a TV. I have a few ones but nothing as old as this. I don't have any plans soon for it as it will probably have to wait at least until winter. As far as parts how hard are they to find for this one? It doesn't have the back but I think I can fabricate one. I looked up the sams for it and it is 91 IIRC. My set starts at 92 and I have some older volumes but not all of them. Mine go from 92 to about 15 years back. I looked and found info that it may be in the Riders TV repair manuals but I only have the radio books. I guess that will have to be the first item to find. Does anyone know how hard it is to find a picture tube or the HV coil? Those are two parts I hope to not have to need. Anyway here is the picture of it. Not too bad of shape.

In the 1000 series that model used to always be overlooked, but I personally love it. I also have not seen a whole lot of them through the years. I do not restore chassis, but I do know that those early Philco's have a lot of caps and require a lot of work to restore. I had two early Philco TV's, a 10" 48-1000 and a 7" 49-702. I parted with them both because of tricky audio problems. Those sets are notorious for that. They sure look pretty though! Good luck.

It might be easier to find a CRT than a flyback transformer, but perhaps both of yours are good. If you don't have a CRT tester, this article explains how you can test the CRT's filament to tell if it's a complete dud:

A picture tube can have a good filament yet be too dim to make a brilliant picture; it might make a good enough picture to get you through the restoration, anyhow.

This site has lots of TV manuals, but I don't see your model listed there unless it's covered under another model number:

Tube TVs are similar to tube radios, but more complex and with higher voltage. This section has some TV restoration articles that may give you a general idea what you're getting into:

If that's a 7" set, it doesn't use flyback sweep.
Is the set simular to the 50-701.

That does look more like a 7" set, duh. I take back what I said about a CRT being relatively easy to find. 10" CRTs are more plentiful than 7s. Anyway, maybe he lucked out and this one is fine. I guess we'll find out next winter, if that's really when he's going to work on it.

I have seen several of these and they are indeed, 10 inch sets. The layout is similar to many 7 inch sets, but the cabinet is larger. Without a scale reference, the picture is deceptive.

As for size/reference, it looks like it's sitting on top of an old Bell and Howell projector cart and hanging over!

Nice set, I think that might be the first one like it that I've seen. fixed yer typo too....:)

I have a couple of early 10 and 12 inch Philcos that likely use a similar chassis... the center to center spacing between the two outer knobs on my sets is about 8-1/2 inches. Using that as a scale, this set must be something like 24-25 inches wide and 13-14 inches high.

Yes, the knob layout looks just like my 49-1240. Could be much the same chassis, only with a 10" CRT mounted on the side instead of a 12" mounted above.

I still have the guts and CRT from a 49-1040, which is also a jug-over-the-chassis.

Look, Pal, you REALLY oughta fix a few of those radios B4 you go tacklin' that TV..Get yr Feet Wet in restoration, so to speak... That's a NICE set, I for one. would HATE to see you "Booger it Up" from inexperience..

Those sets are big, not tall but as wide and deep as most consoles.

The entire front grille and screen comes of the cabinet for cleaning, I don't remember just how but there are a couple of screws you remove or loosen and it lifts up and off.

Thanks for the replies. I am not as familiar with one this old due to the fact when I use to tinker on TVs most of the time it was late 50s to 70s models. It is on a old bell and howell cart. As far as the size that sounds about right at 24 wide by 14 high. If you saw the one Ron Ramirez it is the same one, I got this from him over the weekend.

As far as experience I am not too worried about messing it up. I have restored in the hundreds if not thousands of old radios and worked on TVs as well. I have made my living in electronics and computers since I started working. I use to get old tube stuff when I was a kid to learn electronics as well. About 15 years ago I was well known in my area for this type work. Currently I have a philco 70 I am restoring though. This one the chassis is rusted a lot and the wood in front of the speaker is busted. But it looks to be a good rebuild. I currently have the tuning cap dissasembled rebuilding it.I am thinking it will be at least the winter before I can work on the TV due to so many other commitments.

I do have a B and K 370 model picture tube tester, I will see if it tests it. The main thing I need to do is to find the service info on it. I have riders 1-20 for radio but none for the TVs. I also have a few of the sams from the fist up to about 90 then I have a complete set from number 92 to about 20 years ago. That was when the shop closed I got some of them from. I have tried to find all of the sets I can. The bad thing for me though is I looked up the sams and I think it was 91. I don't have that one. I do have a lot of philco service info from the 50s so I will look through and see if I can find anything.

I use to have quite a few NOS flybacks from back then but I gave them away years ago. Oh well. I am in no hurry on this as I want to take my time and fix it right. So first thing is to look for some type of schematic. Then I will go from there.

I will look at my collection of Wallace TelAid books, I think I have the factory schematic which is better than Sams, except there is no photos pointing at the components.

if I have it I will PM you. That is one neat Philco.

It's good that you have background in radio repair, so often I've seen somebody pick up an old set that's "Talked" to them, & tear in into it, & then end up scrapping what COULD have been a most promising restoration..

Thanks Dav I appreciate that. Sandy I have worked on tube stuff since the 70s. Back then folks would give it to you to get rid of it. So I got all I could, radios TVs and other junk to tinker with. When I was about 14 I worked a few days with this older repairman in his building .I would love to have the stuff in there now. It was about 100x200 feet and two stories full of old items like this TV. I worked on on a lot of old stuff , I was even in a few magazines back years ago with old radios stuff. I got busy with life around 92-94 and mothballed the tubes. I got back into them a couple of years ago after my daughter went to college. So I am back in the hobby again.

I got the old B&K 370 picture tube tester out. It took the number 10 socket. I tried to get it on but one of the pin holes on the socket of the tester was not drilled out. It didn't have a wire in that area. I drilled a hole in the plastic socket so that the tube pin on the tube would go into the socket. I was able to test it then . It went into the Good area of the tester so the picture tube will be good to use. I need to find a picture of the back of the set. I need to fabricate a back for it. It didn't have a back.
