Sanyo C55 Plus preamp with original box - works great with the exception of there is a tiny bit of static while adjusting volume but goes away after the knob is adjusted. The filters, balance and everything else works as well as I can test it, so it is priced accordingly. I had it in line with a vintage Kenwood power amplifier and later a newer Sony 2-channel receiver and it worked great! Unfortunately, I cannot guarantee that this preamp from 1979 will run perfectly until the heat death of the sun, but thats the risk with something 45 years old. It works for me!
