Again arrive to me this broken amplifier.
This is one 4040DSM by the punch.
The power source is blown.
I find two different mosfets; are two IRFZ44 and two IRFZ46.
¿What are the right part number?
¿Some one remember the right part for the drivers? I view two resoldered marked like “2A”
The rectifiers diodes, one is resoldered (maybe changed) marked LM7915CT and the original is 7815CT.
The amplifier section, apear be fine.
I will buy some parts today from Newark. ¿should I buy any more to prevent time delay?

An externally hosted image should be here but it was not working when we last tested it.
