Hi Doug !
I found the hum problem, it was a bad connexion in the heaters board, the same main transformer winding for the two boards !
I now use séparate transformer windings for each heater board.
One problem remain, sound is a little harhs and I suppose some ringing with the interstage.
When I tried the monoblocks whith pentode mode and cap instead the interstage trans, the sound was more easy on ear.
I will investigate with a scope soon and let you now.
Need advices.
Gilles.
