I've done it again, folks. I've purchased the worst PIONEER receiver on eBay! I bought this unit advertised as untested so I really had no idea what I was getting myself into.

Imo these Pioneer 50 and 80 series of receivers are some of the most beautiful in the world, I just absolutely adore the look of them and I can't wait to see this one returned to it's former glory, I'd kill to have one someday.

That hum is a power supply hum (filter caps probably), not a ground hum.

The center vertical PCB has four (4) low voltage, differential power rail electrolytic capacitors that are dried up. I had the same exact issue with my Pioneer SX-750, except the AC hum on my unit was much worse. The ESR of the electrolytic capacitors was through the roof. The large, high voltage, electrolytic capacitors are usually fine, btw. Fred

Great basic diagnostic video for unknown receiver. I personally would have hit the controls with some contact cleaner BEFORE I started testing, no sense wasting time diagnosing a bad channel when it's just dirty controls!

SX-750 is one of my favs. When working properly they have a nice warm sound and plenty of power. Start with a good cleaning and spray the switches and knobs. they sell recap kits for this model. Well worth the work in my opinion.

Clean and inspect. 1st step. Will not come in the house without getting dust blown out and the exterior dissinfected. Lysol wipes work great to cut smoke and grease. Then switches sprayed by default. Then power on. I spay each board induvidually with electronics cleaner and scrub with various brushes and collect residue with cotton swabs and micro cloths.

I've bought a few "dead" units at garage sales and such...compressed air lightly for dust...then 40 turns on each switch and finally deoxit. Turn on and wait for smoke. Then tuner to see if it locks stereo. And finally speakers...speakers that I won't miss if they pop. If all goes well it's a wash and picture time...
@martyjewell5683
@martyjewell5683 2 года назад
As vintage receivers go, this SX-750 ain't half bad. Healthy power, bidirectional dubbing, nice looks (when clean) and good specs. Just never liked the power and speakers on the same switch like the SX-650, 550 and 450. It does have a muting circuit for speaker protection. An old friend had this SX-750 driving EPI-200B speakers and sound was impressive. Hats off to you for this project, I ain't got the patience (or knowledge) to tackle this.

On the power supply board, C17 & C18, (330uf 50v), will be tired. There's close to 50v running through them and their proximity to the hot transistors really wears them out. Upgrade to at least 63v and 105°c replacements. 👍

My brother bought one of those brand new back in the day... LOTS OF POWER!! At less than half volume it would knock pictures of the wall of our old stone farm house. I have a "90 watt" Yamaha av receiver and its not even close at 3/4 volume to the old pioneer. Junk. That said I had a little Sansui 30 watt that amazed most with how clear and loud it was. I dont remember what model it was but from the early 80s and black.

That is defiantly 120 Hertz power supply hum. More likely the smaller capacitors for the preamp power supply. For some reason they only put 85c rated caps in those positions typically and are prone to fail. Yes, please diagnose this one. You got my curiosity peaked now.

I wish I still had mine. My apartment was broken into and along with the 750 went my DLK speakers my turntable, cass deck, equalizer and CD player. Oh, lest I forget, about 1200 dollars in CDs. Not what one expects to return home from work to discover. Before that fateful day, I had moved more than a few times even out of state and my system came through it all, never giving me one moment of grief. A true workhorse that could rival Gabriel's trumpet.

I got one of those from my uncle & man that thing was so fookin loud. I used it in the early 00's & it still slammed but had crackling issues w the pots sounding a lot like the one you hooked up. One night I was listening to something low & quiet when I swear I heard a thunderbolt right next to me which scared my dog so bad she jumped, yelped & shit all at the same time. The noise came from the Pioneer and it stopped working right then. There was no smoke. I cleaned up the shit.
