Good Day!
I recently took on the task of putting new capacitors in my old Yamaha P2200 amplifier and at the same time I'd like to add some speaker protection to it. The speaker protection relay board requires 12V AC to operate. I was curious if I can steal this AC power from the amp itself rather than adding a wall wart? There's a convenient point on the driver board that is 13V AC straight from the power transformer.
My questions are:
Is this a safe thing to do?
Will it affect amp operation?
Would the chassis be ground?
Will the 1V difference matter?
