Hello,

What is the mains voltage?
Maybe the DMM is wrong.

EDIT: Heatervoltage = 6,3 V AC ?

Hello,
Thanks for your answer  :topjob:
My DMM is an automatic ac/dc multimètre which give 235V on the L-N and L-ground of the amplifier.
I will measure the 6,3V heater and inform you about the result and other measures comparaisons with the schema's ones.

Regards,
