Ack! I looked again. The markings are just about rubbed off - it looks like it's 237. Grrr. That's the best I can tell
I'm holding the light at funny angles to see if i can see anything, that's the best I can tell. It's certainly 23something, I can't tell if the last # is a 4 or 7 or what...
The sweep sections seem totaly dead, though the flyback didn't seem blown. Might just be a lot of bad caps, or a bad tube or such. I did get some audio action and that's always a good sign.
As typical, the set needs a new HV suction cup. Man, those things deteriorate....
I'll probbably start tearing into the caps this week or so, at least get what papers I can out of the way.
The horizontal oscilator tube socket is rubber isolated. That's weird. I can't tell just yet what tube the vert osc/output is - probbbly one of the many 6SN7s on the thing (I counted 5) Magnavox must have gotten a deal on that tube, they used it everywhere it seems. There's also an oddball 6SF7 in there. I think that's the audio amp - it's right next to the 6V6 output.
