Silvertone 113/110.700

[mr_rye89]

Look what followed me home today! 1949-50 I think, built by Air King maybe. 12LP4A picture bulb. Knobs, HV cage, rear panel are all present, 5U4GB isn't lol

General Electric CRT ? I'll bet its still good.

[mr_rye89]

Yep the (GE) CRT is good. I found a burned 4.7k resistor on the damper next to a sketchy looking wax paper capacitor. I may swap those and see if it will come up on dim bulbs. The dang schematic I got is the wrong one, but is similar enough that it took a while for me to figure out. Reading those pf value molded paper domino capacitors is a real pain

Very nice find.

I located in Riders 5-1, as Air King models 12T1, 12T2, and 12C1, chassis 700. Your Silvertone version is way out in Riders 10-1, and they show the exact same schematic as the earlier Air King (drawing number 5958). Seems like the Sears chassis no. 110.700 even corresponds to the Air King chassis 700. It appears they used that same chassis with slight modifications with every CRT size under the sun, including rectangular ones. Oh and you probably know it's basically the same Air King chassis in Sams 121 folder 3.

I couldn't find it in Rider's There's a burned resistor on pin 3 of the damper (6W4GT) the (wrong) schematic doesn't show any resistor on pin 3.....

Here's a couple pictures from Riders. Unfortunately I have no way to scan these large pages but these pictures turned out quite clear. If you left click on you can zoom in.

I might have a physical copy of the Sam's folder for this TV in my Sam's Photofact Stash that I could upload or email to the OP.

I'm sure that would help with the visual orientation when locating components.

That would be great if it's not too much of an inconvenience

Some Sears sets seemed to be regional. We never saw too many Sears sets built on the east coast or the west coast.
Most of the sets sold in the stores in the mid-west were built by Arvin or Warwick, with a few Stewart Warners thrown in!
There must've been some bad blood between Well Gardner and the Sears buyer, as I never saw a Sears set built by them.

[mr_rye89]

Wasn't Air King based out of Brooklyn NY?

Anyways I just ordered the bulk of the replacement capacitors for this set. Do the 24pf 3000v capacitors in the horizontal section need to be mica types? Multilayer ceramics exi$t but are on backorder.......

[AlanInSitges]

What a sweet set! It was probably worth more as a 5U4

Looking forward to see progress on this one.

Are you still running it with all those old paper caps in it?
if so you you are lucky you are getting it to do anything at all! :O

[mr_rye89]

Mostly original caps. Hv rectifier is 1X2B. I wanted to see if I could get a raster before doing a recap job. And I’m pretty sure the horizontal is running……

[jr_tech]

Is that an “air arc” , or is the nut driver grounded?
