Naylor Super-Drive 60 KT66 bias

[mom]

Whats a good starting bias point for KT66's in a Super-Drive 60? They're Chinese (Valve Art), if that matters.

What's a Super Drive 60? What's the Class: class A, class A/B, class B? Fixed bias? Unadjustable bias? What's the plate voltage?

Need more info. I'm guessing Class A/B fixed adjustable bias, correct? Plate voltage is essential. Have you biased amps before? Is there a test point in it? Do you have the 1 ohm cathode resistors that make reading it really easy?
