Probably not

I am struggling with a SV-226 MKii

Speaker relays are not energized.
Headphone output works, preamp and poweramp sections are ok.

Replaced a few bad transistors in protection circuit, but there is little space and to be honest I do not yet understand the protection circuit.

FIXED!

Replaced just a few C9014, C9015 and 2N5551 transistors per channel.
No idea why they failed though.

Hope my random comment helps someone someday.

Vincent is a bit secretive. They do not even have a contact e-mail.
They just refer to their distributors.
I did not even bother to ask for a schematic.
