Need a little advice here. I have a TKO80, had it since about 1983 and the thing has always worked great as a practice amp. It just started cutting out on me, mostly when I play loud. Changed cables and cracked open. Other than some cobwebs that I cleaned out, the circuits at least look fine. the only thing that may need replacing is the speaker which is the original 12' Scorpion. I was about to replace it anyway but now just considering whether to just buy another combo. I hate to part with something but dont want to throw good money at it if its a lost cause.
