re: A-9

I just bought a New Old stock one of these as I am building a top end 1983 Pioneer System. Great Unit. Adding CTR-9R deck and F-9 Tuner.

re: A-9

Great amplifier . Been using it for around 4 years now . I got it from someone at an OK price . Runs well, output transistors were replaced once on the left channel due to bad fluctuation of electricity in my area . But so far so good
