Just got a Custom 50 amp. What is the correct bias for 6L6GC Tubes? And what about EL34 tubes?
Thanks in advance.

Bias settings for Custom 50 Amplifier

It's going to vary from amp to amp, not so much tube type.
As an example, on the DG Custom 50, for the EL34s it comes with the recommended bias is +/- 67 mA, while the recommendation for my HXDA with the same tubes is +/- 35 mA, if memory serves. Of course, the DG50 has two fans, and is a different design.
Since the manuals generally don't specify the recommended bias, I'd call or email PRS customer service. I'm sure the email address and phone are on the PRS website.
