Hi Patrick.
You do it by turning VR1 and 2 while probing either R9 or R10 for 100mV and output for 0-5mV. In PMI's boards VR1 and 2 are in parallel with R5 and 6 so start the amplifier with these trimmers set to maximum resistance and always keep an eye for R9 voltage during turning.

Maybe it is too early, but i would like to ask if there are any plans for V5 amplifier? A slight chance for that?
For 56V supplies, 63VDC rating or higher will be fine for 470uF. For the 2200uF 6.3VDC is sufficient.

A quick question.
For V4H - what is max PSU voltage if caps are up to it? (maybe it has been said before 🙂 )

I have tested it upto 56V. I think it will still work at 60V but we get too close to the limitation of the small signal transistors, so 56V is recommended maximum.
