CHAMP ELECTRONICS -" THE VINTAGE VALVE AMP HOSPITAL"
REPAIR OF AN AMPEG MERCURY M12 COMBO AMPLIFIER
Belonging to a real nice guy and customer of mine (Pete), this amp needed a good general service
and check-out as it wasn't sounding too well!
As first removed from the case.
As above, but with the removal of the now-diagnosed faulty output transformer.
The re-wound output transformer.
Not the original driver of course, but Pete (the owner) likes the sound of her with this Celestion Vintage G12
Nice old amp!
