I got this amp so I can shoot DX when I go camping.. was running the RM KL503 with my cobra 148 all I did was use it on low power pushing about 10 watts max SSB in to it, and getting 110 watts out. and I was sound ruff to people... so I took it with my 148GTL to the shop get set up well it came back bad predriver he replaced it with a IRF520.. ok cool I used it a few times pushing 100 watts on setting 1 no complaints. and now every one tells me it sounds like trash... WTF...
Ok before I just through this in the trash.. can I replace the IRF520's with IRF540? will that help beef it up?
And I am looking ac the kl503 schematic and this looks to me like a class C not a Class AB :sad:
if I cant save this thing I am going to strip all the switches and fuse holders out of it and through it in the trash
