Yeah--there will be a trim-pot inside the amp; you'll need to remove the chassis to do this, not go through a hole from the outside like some Fender amps. Be very careful about this, though, and only proceed if you have experience working with guitar amp circuits. Deadly voltages may exist inside there.
That being said... Dr. Z's website shows that you should expect to bias at or around 33 mA plate current for his recommended Gold Lion KT-66 tubes.
Own or have owned: M12, Carmen Ghia, Rx JS, MAZ 18 Jr NR, Monza, Z-28, Route 66, Therapy, DB4, Remedy, Prescription, EZG-50, SRZ-65 LE, & Delta 88 Z-Drive | Brake Lite SA & Air Brake
I have a Therapy and love it. I traded a Z28 I had for sale with a guy that had a "dote for sale and when I first got it I was like..this is loud (and it is) wasn't sure about the tone etc,long story short..I play the Dote more than the therapy.Still love the Therapy and miss the Z28 but Dote is on its own category and that Tone bypass is thick like molasses
GuitarZ: Ugh! Dropped small nut while installing new outside lamp. Thought I saw where it landed. Couldn't find it. Moved the car & such. Engineering mind said, drop another (after ~hour). Bang! Within 5 seconds. Nut found! Yea! Wife Impressed!

GuitarZ: Bells & Whistles-New Cars. A year with our Subaru Outback, finally realized doors have to be unlocked for inside rear hatch button to work. Dang! I need that feature for social distancing. Looked like an idiot pulling up & jumping out to manually open.

GuitarZ: Best Pandemic Comment - Delivery guy shows up. As we're social distancing, I look at myself in brown loafers, black socks, gym shorts, t-shirt and say "I realize this is not my best look". His response "You can wear whatever you want to the apocalypse."
