Is the JJ jr Cathode or Fixed biased?

[psychodave]

I’m just curious. Based on how it sounds I’m guessing cathode biased?

Cathode

Cathode

Do you know this for sure? How?

I would presume cathode biased too, as production efficiencies would dictate using the same PCB for the JJ Jnr as the other smaller amps, but the inclusion of the Presence control has me intrigued. But it could be a sample cross line RC setup like the old Vox amps Cut control wired in reverse.

Yes that means when rolling power tubes it's Plug n Play

Are the PT20 and DS mini also cathode biased?
