Vintage Asylum Classic gear from yesteryear; vintage audio standing the test of time. |

I recently received an H/K 430 twin powered receiver from someone who hadn't used it in about 20 years, and it WAS working when they stopped using it. Now I hook it up after replacing the fuses and no sound comes out other than some low frequency noise that pumps the woofer cones like crazy and some harsh buzzing noises intermittently. Does anyone know what might be causing this? I know the easiest thing would be to take it to a repair shop, but I just wanted to work on this thing as a hobby. I've got a ton of capacitors and resistors from building headphone and class D amps, so I could repair it myself, but I don't have to knowledge to diagnose the problem.
