I've been asked to look at this thing, looks like an old k1313.
Klv250, rm italy mosfet amp.
I'm a glorified tinkerer, tinkerist? I can solder and have some old test equipment, and some knowledge, but far from an expert, and not and amp guy, so please forgive any ignorance.
I don't have much experience with mosfets, I've been away from the hobby for a while.
The amp...
It has been blown up a few times.
The 4 factory rm3s? had been replaced with irf520s which were blown, then replaced with new rm3s and blown up again in a day or so.
My questions are, would anything have been changed to make the 520s work, or are they somewhat drop in?
From what research I did the rm mosfet info is top secret.
The amp currently has the mosfets taken out, what should I look for as far as voltages etc? On high vs low, Or any other ideas of possible problems to look for.
I don't want to just throw another set of mosfets in just to have it pop again.
If I can go by 520 specs to look at voltages then I can figure that part out.
Should I be using a vtvm or would a dvm be fine?
I thought I'd ask here to hopefully save some time when I get it back on the bench.
