Fortè model 3 schematic

[passante]

First, sorry for my very bad English!!
I am an happy owner of this amplifier; I bought it twenty years ago about.
A few days ago I noticed that the right channel does not heat more like the left channel, but the output sound seems still good at low level.
Someone has the schematic, to see which is the fault?


Thanks in advance
Marcello

As I recall;, it was nearly indentical to the Forte 1 schematic,
except for the power supply voltage and bias setting.

Thank you, Mr. Pass; I hope to resolve the fault. I think it can be caused by the trimmer R15

Thank you very much.
