Yes, your drawing is fine. And raising R6/R13 to 1k completely stopped any hint of oscillation, no matter what the gain.

Measured frequency response with the pot at output extends beyond 100kHz.

Someone was asking if Dale RN60s fit or not... yes, but they are tight. As you will note from the pics, a couple of them sit above the others. Hopefully this won't be a problem, but if you think it might be, let me know.

Have you considered / tried mounting some of the resistors on the bottom side of the board? i.e. alternating with 1 resistor above and 1 below? It might work...

Well, it will work the way it is now... they are all soldered in. That is a good idea though... I may move 2-4 of them (the ones sticking up) to the underside of the board.

Hello Veteran

I would like to buy a set of Ap1.7 pcb's; gold or tin plated for 2 channels-whatever is available.

Thanks, much appreciated🙄 🙂

Peter or Vetran

I was confirmed on the list for 2 sets of gold plated boards. I never received the final shipping amount so I have not sent payment. I have sent a couple of emails to Peter but have not received a reply. Would one of you reply to me and let me know if my boards are still available?

Kind regards,

Paul
