My first integrated amp was this SA-8500 and I really enjoy the crisp powerful sound. John

Great video! Very educational with the steps you go through analyzing the fault.

Great video, and a beautiful piece of equipment.

Excellent diagnostics and repair.

Man if i could do it all over again i wish i studied what you did! I have a Pioneer SA5500 II i would love to overhaul like that! Inspired me to get it from the garage and use it! Thanks for your insight and expertise! ( Regardless if I understood all of it lol)✌️

I just bought for a good price ($150.00 Canadian dollars - shipping

very good Restoration sir

Excellent troubleshooting job

Repairing electronics looks so fascinating when observing the work that is being done.

great video, just scored a 7500 mkII

I am so grateful, for your sharing, generous personality, ways, object, and the sheer thought of all knowledge you just let me take part of for Free! You are humble, go through stuff with patience, and, to be honest, I can even find salvation in seing a video, it just proves some people are good people. Thank You So Much. Can I support you in anyway? Shame, I am in sweden and my inherited and beloved monster Pioneer. A-858 ( sold in europe, also sold as A-71 overseas tho), well, I shorted it and understand it is gross, I wanna restore it, somehow, with 1000 W marked power, and 2 x 27000 uF, 80 V. Capacitors, 24 kg. It should be put to life. Is there any US. amp that might be similar to this 1989 only, Reference Amp? Anyways, rhanks. Take care, keep up the great work Tony!

a lot of hard work there

Thank you for taking the time to make and share this video. Would you please share what transistors you used as replacements?

I enjoyed this. thanks!

Thank you very much ...awesome video !

An interesting video as I am trying to understand how amplifiers work. Can you explain how you set the quiescent current in terms of how you connected probes and measured the current? Thank you.

That was awesome! Thanks mate

what a beauty. built like a tank

correct me if I'm wrong, but a good take away from your video, is that when the power supply is at fault, a basic rebuild of that unit won't hurt and save time over testing every part, since this is such a well build machine, it just makes sense for the longevity

by changing the capacitors, will that take away from the sound? These amps had a lot of speaker pushing power. I was under the understanding that, that is where they got the power, from big old capacitors.
