Looking for HH electronics schematics

[Empee]

Hello all,


I'm looking for the schematics of a HH Electronics V200 amplifier.
It's a passive cooled, SK135/SJ50 mosfet PA amplifier.

And does anybody know the bias-procedure for this thing ?


Cheers,

Empee

You could try HH Support | HH Electronics
or HH Amplification - We are an independent Company who cares about HH Amplifiers
Their site though displays errors when
trying to access the V200 manual.

also general info here: https://en.wikipedia.org/wiki/HH_Electronics

It is similar to the VX450 but fewer output transistors. H&H recommend setting the voltage between the gates of the Fets (Gate to Gate of 135/50) to 800mV. The Fets will warm slightly and equalise, just like valves do so no need for equalizing resistors in the sources.
