[quote author="Jazzy_Pidjay"]i have the same "low" voltage !
HT about 208v when the 4 tubes are pluged in.
The two main trafo are 30VA

We have kind of the same problem: For testing purposes we used 12AX7 tubes on our G9 first, which should be at least pin compatible to 12AU7. It worked fine, HT voltage was about 250V.
After putting in the proper 12AU7 tubes, HT voltage dropped to 230V. It´s working fine nevertheless, so we don´t care really, but we´are interested in the background of this drop. Anyone?

Edit: We´re using 30VA transformers also
