Bugera Infinium: V22 and V55 schematics

[Steve A.]

There is a link here for the older V22 and V55 schematics. A friend first bought the 22 watt then returned it to GC for the 55 watt which he may return for another 22 watter. He wanted to know the differences in the preamp design. He was also wondering why the Main Amp In jack produced sound with V2 unplugged but not V1...

Thanks!

EDIT: I forgot to say that the OT on the V55 Infinium is magnetic- it grabbed the screwdriver out of my friend's hand- this with the amp off!

I had already checked those but could not find the V22 Infinium in particular. The earlier models have a bias pot and test jack, the new model doesn't.

Thanks
