Here is the replacement for the Fisher 500C. This Fisher 500-TX is a totally transistorized receiver and this one is un-restored but operative. In an original 1969 Fisher catalog, Fisher claimed RMS Power(1Khz at 8ohms) to be 65 watts per channel. Quite a bit of power in your living room of 1969 in my opinion. It's a real nice receiver when considering all that it does have and you could have it with or without that nice walnut cabinet or the RK-30 wired remote.
