you almost need a DIY vented paint booth for that kind of work, that way you could do it all seasons.

Hi Bob,

Well, I picked a GE 810 and a Philco 49-1040 tonight. So I will continue to follow this thread and the GE 810 thread with great interest! Nice work so far. I hope I can do as well.

Yeah, a paint booth sure would be nice

I picked up some reproduction rubber corner mounts. I've used these in radios before and they work great but was wondering how well they would work on this heavy chassis.

Mystery solved as soon as I pried off one of the rock hard old ones. There are metal insert reinforcing them.
I slid these into the new mounts and they work great! The control shafts line up perfectly with the cabinet holes now.

Next up, I'm cleaning the knobs. It's nice to have a complete set for a change.

Note that this set has an aftermarket "channel adjuster" control added onto the contrast control
That's a potentiometer with a switch wired up like this.

What does the Channel Adjuster control do?

Bob,

I have the same issue. Did only two of the rubber mounts have a metal piece in it? I only found two in mine (Don't know which locations) and who knows what has happened over the years.

While I won't be able to start work on mine, I did check the CRT and it is low emission. But that will be good for a start.

Fine tuning. Seems to have worked like a varactor diode somehow. I guess they figured owner's wouldn't need fine tuning originally.

All four had the metal shims. Maybe you can fabricate a substitute ?

Looks like an AFC circuit in an FM radio. This can only work if the TV set does not use the intercarrier trick (4.5MHz sound IF taken off the video detector diode).

Thanks Bob. I suspected that! And yes, should be easy with patience to make "New" ones! Great thread...

Right you are. It's a split carrier with a sound IF of 22.1 Mc.

I decided to repaint the metal outer knobs. Kona Brown was the closest paint I could find. I stripped them with some citrus stripper. Some of the ol dpaint was really stubborn so I just sanded them smooth. Then, primer, Kona Brown and a clear coat. I used Simichrome metal polish on the knobs.
I think they turned out pretty nice.

yea they look new again.

I believe the dealer would pop in up to eight tuning strips for your particular area.
How strange that the first position is labeled "1-2" in 1949. Perhaps this plate was used in earlier Philco sets too

The rest of the sequence is 3, 4, 5-6, 7, 8-9, 10-11, 12-13.

I'm considering fabricating a new one from scratch or perhaps someone out there has a spare one in better condition ?

Bob,

Can't tell you how good it looks.

It is with great curiosity that I watch this phase of your restoration. The one that I have on my 49-1040 could be a twin of yours! I unfortunately will not be able to work on it for a few months. Got houses to sell and moving to do. Not looking forward to that.

Hey, there's someone selling an empty 49-1150 cabinet.

Looks like it's walnut. I had no idea they came in anything other than mahogany.

I've seen a number of them painted white, as well. Can't be too sure if that was ever a factory finish, or just part of the painted furniture fad.
