looking for some fets 125n06 motorola looks like a pretty standard fet 75v 55a but the resistance is very high anyone know where to get some I have 2 amps to repair that require the same fets or a good replacement
Generally, on Motorola FETs, the part number indicates the basic specs. The 125N06 would be an N-channel, 60v, 125 amp FET but I can't find anything like that.
I think those are more likely to be 25N06s than 125N06s (rated for 25 amps vs 125 amps).
I'd suggest using something like the IRFZ44 with 100 ohm gate resistors. The 470 ohms gate resistors will need to be replaced for virtually any FET that you're likely to use.
I did some research, it seems this same question has come up in here before with the same amps lol, and the 470 ohm resistors were brought up as well, I will give the z 44's a shot, both amps have the same resistors all measuring the same.
