I have a Memphis Mojo 2500.1d that I picked up in non-working condition. Upon opening it, I noticed that qa1 and qa3 which are mje182 transistors were blown. Somebody had soldered across all 3 pins on qa3 for whatever reason, I guess in an attempt to "repair" the amp. There is also a burnt resistor, R18. Does anyone know yhe value of that resistor? I can't make it out. Also, any thought on what else I should look for? It appears that all output fets are good. Thanks.
