Well after seeing that the parts I had used for replacement before appeared to be fakes I decided to give this old dog one last try.I replaced the IRFZ44ns with FQP50N06's because fairchild had it listed as a direct replacement on their site.I also replaced the 2SA1265N's and 2SC3182N's with FJA4210's and FJA4310's.I used a ten amp fuse on each side for initial power up and although the amp powered on it idles very high (around 10A) and starts to slowly rise.Just wondering where I might look from here.There is rail voltage present on the outputs verified by a quick check before I shut the amp off.Do I need to change the gate resistors for the new power supply fets or is the FQP50N06 not a good choice for this amp?I'm admittedly lost on this amp.
