RE: 6N1P

Posted by Jonesy on January 15, 2023 at 18:07:46:
That reminds me of certain brands of signal tubes that would never allow me to dial in the DC balance correctly and hence biasing the output tubes. Nothing wrong with them. Just not a good fit in my (40 year old?) but still in use ARC D70.

It may be the same case with the 6n1p.

I came across some medium and high gain 6n1p on the web. I wonder if that would make a difference to making the adjustment. Maybe your tech friend would know and it would help you refine your search.
