Default GU-19 In priboi

I got the GU-19 tubes and tried them right in the Priboi.
Anode = 480V
G2 = 240V
G1 = -20V

I can't get lower yet with this chasis, I guess -15V should be better.

The sound is OK, Sad thing is I don't have a proper model. Any ways I could wire the transformer to give 420V instead of 480V ?

No fan needed, well yet...

The design quality of the GU-19-I is amazing compared to the 6R3S ! What I need now is a proper spice model for that lamp. At -25V it start clipping.

Hi there! Long time no see...

Quick question, have anyone tried viceversa? I mean replacing FU29(GU29) with 6R3S (Proboi-like) into an amplifier like this one? AUDIOROMY "FU29" Integrated Amplifier - FU29 Tube Amp @ on9mart.com

Thanks!
