adjusting BAT VK-3i

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Hello folks,
I replaced the tubes in my VK-3i with NOS Tesla gold grids. The difference is amazing. The highs are very fluently and lows more structered.
What I noticed now is the noise coming from my speakers (was also before the tube change). It is not produced by my power amp. I noticed there are 4 rotary resistors near the tubes.
Since I live in Holland there is not much nowledge of BAT products yet. So now I am looking for the function of the 4 rotary resistors to adjust them, and even better a circuit diagram.
Does anybody now the function, and what is been adjusted by them?
Thanks,
Ed
