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...
