I adored these Pioneers of the '70s. My first receiver was an SX-580 accompanied by a CT-F500 cassette deck and a PL-520 turntable. Over the years, I upgraded...but the "upgrades" never had the mind-blowing effect of my first stereo whose components I chose myself. These is a lovely receiver, and I hope it will continue to serve the new owner well. Mahalo for saving another electronic masterpiece from the landfill. Aloha.

Ahh man! That’s a sweet system. The first one always seems to stick with us. The new owner seems quite excited about it and I’m also happy it didn’t end up in the landfill. Cheers 🍻

Those old Pioneer receivers were the shit back in the day. My brother had a late 70s model that just blew the roof off of every place he ever lived!

They’re beasts! Sounds like some good memories with your brothers and probably some great parties 🤘

Tip! The push switches basically are the same from one switch to another. I lucked out at a local Army Navy surplus store and found a similar switch with a different pinout but the parts you really need, the contacts', little springs, big springs are what you're after. I now have a film canister filled with these parts and the funny thing about it, I hardly lose them anymore I think because I know if a spring takes off, I'll have plenty of backups so not so nervous handling them. I think that I once suggested pipe cleaners, folded a few times to get at the contacts inside the switch, and also great, straight into old tube contacts polish them right up. One last method I've tried and works are those Mr. Clean, white scrubbing pads but that method requires you to make a very nice cut of the pad or it catches on the inside and sheds material. It needs to be cut like twice the width of the opening and compressed in a way to get it all the way in the switch. Not that difficult, I figured out a repeatable near screwup free method of using it but I think you would need visuals of it and I can't get photos to stay up. I should make a KZbin video.

Nice! Thanks for sharing this. Solid tips for cleaning the switches.

Do you have schooling for electronics? And from 1 to 10 being hardest! Could a novice start doing repairs on these amps, or is it much more than just that?

I do not but I’ve been working on electronics since I was in high school (around 15 years). I have done a lot of reading and still have a lot to learn. It’s very possible to do basic repairs and such without much knowledge but there are lethal amounts of electricity involved so you should at least do some reading in regards to basic circuit and have an understanding of how electricity works so that you can be safe. There are some great books out there and lots of forums to read up on. Starting with speakers can be good because there’s a low chance of getting shocked since they don’t directly plug into the wall. Other channels like Xraytonyb are also phenomenal for learning. Thanks for watching!

Nice job. The dial pointer on these is indeed a pain. I had to use my dremel to make a little clearance for the LED. Next model in the line but same issue. thx for the lesson on the switch lubing. Good stuff to know !

Oh man, yea a dremel would be nice to have. Right on! I'm happy it was educational. Thank you for watching!
