SA-P80 power amp, SA-C80 pre-amp, ST-R80 quartz synthesizer tuner, & amp, RC-R500 wireless remote control system with hand remote. Original cables that came with the system were stolen, so wireless RC-R500 won't function properly. Original speakers were sold. I will demonstrate the high fidelity sound of the system on a pair of 8 ohm speakers. Keep in mind this was not a cheaply built 2 channel system. It was an early 80's Japanese system were quality was emphasized.
