I'm restoring a 1980's solid state Carlsbro Wasp Lead guitar amp and have run out of luck finding schematics. Any assistance would be gratefully received. I have ordered new Nichicon Gold Audio capactitors and am considering replacing an NPN transistor that is giving anomolous hFE readings. It's an RCA1C03-C (619) T0220 power amplifier for audio transistor. Compatible replacements seem to be the MJE15032 or the 2SC2810 but I am unsure.
I plan on fitting a new Jensen C8R 4 Ohms, 8", 25 Watts, speaker which is on order from Thomann. I have a suspicion that the basic design of these solid state amps is sound but they suffered from cheap components and cheaper car speakers. (I found an old car door speaker in the last Japanese 1980's amp that I restored. It had been factory fitted.) Any assistance would be gratefully received.
