Many thanks to everyone for your help; I've downloaded the schematics
(thanks !), but it doesn't re****t the transformer output voltages.
I'll try to guess those data, based on the schematics.
If it was not for a frend, I'd have suggested to him to buy another
preamplifier ! But I don't want to leave the challenge now !
