PT-2 motorboating
#2

Hi Karl and welcome,
https://philcoradio.com/library/download...20Book.pdf
You didn't mention if you aligned the IF with a generator @ the proper frequency.
Sometimes wire position can be somewhat critical. If you did replace wiring in the mixer circuit try repositioning for best results. Maybe a little more decoupling may help. Try increasing the value of #7 or #11. Would try shorting out the L portion of #7. There may be something different about the makeup of the new cap vs the original so it doesn't act like it should. Check the bottom (avc side) of the loop ant for a good connection. I trust you checked the voltages around the mixer for anything that out of the normal.

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!
