[R-390] OT: Transistor Amplifier Question

Rats.  I must correct myself.  On the preamp board, those 50pF caps are across base and collector, not base and emitter.

On the phono board, some transistors have that across base and emitter while others have that across base and collector.

As I said, I'm going to stay with the original circuitry but just wanted to correct/clarify my post.

Thanks,
Barry - N4BUQ
