Well it's been almost a year since I've played with this guy. I was getting a bit frustrated with an intermittent problem. I replaced just about every cap and resistor, the IF transformer, the mixer and IF amp tubes, and it was still giving me a run for my money. Would still lose gain and the detector would go out of oscillation. When it was working, about 80 percent of the time it played very well then the volume would drop to about half and the signal would get much noisier. I did find a minor problem the detector plate voltage was down a bit. Was 36v should be 47v so changed the value of the voltage dropping resistor and now I've got about 55v. It's been on the bench for a hour or so playing just dandy. I've got my fingers crossed.

Mine must be an earlier version as it only two sets of louvers in the top

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got it!
