Cathode Bias or fixed?

[withmittens]

Speaking of the RM22. I'm imagining it's fixed as that seems to be common, cathode being not so?

Am I wrong?

To my knowledge all the Egnater and Randall modular amps are fixed bias hence the test points and adjustment on the back. For RM20/22 you’ll use EL84 and bias between 15-20mV.

A cathode bias amp would be something like a Vox AC30, Fender Blues Jr, etc.

I wouldn’t necessarily say one is more popular than the other as you can find many examples of both.
