Thanks to the many people smarter than me on these
excellent lists, I've learned a lot while fiddling-around
with the SCR-183 and the WECO 227B rigs.
Time to get back to re-tubing and stabilizing the BC-375.
Here is a diagram of the BC-375 oscillator in
its native condition:

This is my first idea- to open the feedback to the
OSC grid and feed to Aux Osc. in there.
The original OSC tube will act as a "buffer/amp."

However-it's a triode. Neutralization might be
an issue. If so, how would you accomplish it?
Ground rules: No drilling, hacking or whacking.
Every change must be 100% restorable to original.
