Pioneer SA-7800

Sold for: $405

Years available 1979–1980

Right, my friends, in my opinion, this amp belongs to the most beautiful series of amps ever designed. These are the ’63 ‘Vettes of the audio world. You cannot know how good they look and feel until you have one in your rack. In many ways I think that this one—the bottom of the line—is the best amp. I’ve owned all three in this series and the other two (SA-9800 & SA-8800) have a ridiculous number of levers and knobs. This one in the most manageable for those of us who tend to set all of these in the flat position.

Inside the case is one one mofo of a transformer and 4 x 8000uF caps, so plenty of good, clean power to burn. Very good separation of instrumentation and a super-clean, almost clinical, clarity to the music.  If you are going to buy (invest in) any of this series, it really does help to familiarise yourself with the insides as you will have to periodically clean ALL the pots and lever switches — I emphasise “all” here because failure to clean them all may cause even the most unlikely of contacts affect sound across one or both channels. I have fixed many a misbehaving amp from this series with a decent clean.

No real weaknesses (except for the pots and switches) and the blue fluro meters have never been beat.

    Greetings! I know this is kinda off topic nevertheless I\’d figured I\’d ask. Would you be interested in trading links or maybe guest authoring a blog post or vice-versa? My blog covers a lot of the same topics as yours and I believe we could greatly benefit from each other. If you\’re interested feel free to shoot me an e-mail. I look forward to hearing from you! Superb blog by the way!

    We have two of these amps. One is left from my husband’s college days. Do you know of anywhere I can get instructions on what and how to properly clean all the dials etc?

    Does anyone know a repair/cleaning shope who could do this?
