Hi Walkalone
Yes the USSA5 meets my own criterias but other amps too.
Vssa is an old topology that was made more popular on this forum by Lazycat. Peeceebee is an example of that. Vssa also came from SSA amp. At about the same time both Lazycat and I (and surely others) used the SSA to convert in an “VSSA” topology. Afterwards, I decided to go closer to SSA and make USSA.
Personally I prefer the USSA for sound.

the original poster was looking for circuits using his recently found stash of lateral mosfets.
I'm looking for some help on a Belles 400, J50 K135 combo.
40mv DC left channel
115F output temp
140mv DC right channel
130F output temp
Never played thru speakers yet as I wanted to check bias and try and reduce DC at outputs.
Can't find a trim pot to adjust.
Can't find info on the amp anywhere except a schematic of one channel which I can post as well as internal pics if this would be a proper place to do so.
Thanks

This circuit came from a Hitachi datasheet for lateral mosfets. Maplin copies it and sold hundreds.
has anyone seen a schematic like that that operates with these transistors ?
if so please let me know
