Pioneer exclusive amplifier repair needed


Have two amps in need of repairs. 
Exclusive M4 stays in protection mode after turning on.

Exclusive M10 Left chanel out. Meter goes to half scale after power on .

Is there any one who still  repairs this vintage pioneer equipment ?

Thanks,
Jeff Tolbert
