The Pioneer SA-8500 is a 2-channel integrated stereo amplifier featuring defeatable, twin bass and treble controls, I love the microphone input with level control. This unit is great to work on, easy access and schematic was awesome. The relay was giving this unit some issues, check out my special effect sound, you may like it especially if you're a Star Wars fan such as I.

Love these videos. I’ve resurrected a few HH Scott integrated tube amps (299, 299C & 299D), but never tackled solid state. As a beginner, these videos have been extremely helpful. Thank you!

Thanks Joe for the video! Build quality was impressive on this Pioneer. One of my favs of this era was the Luxman L-11.

God knows I love Luxman....

Thx Joe. Great closeup on the relay cleaning. I've 2 Marantz receivers in desperate need of similar TLC.

Great timing! I just picked one of these up. haven't hooked any speakers up to it yet but it looks good on the dim bulb and the relay clicks in. I've been replacing the relays instead of cleaning them recently.

I had the Pioneer sa-8500II with two power supply and 4 capacitors. That amp was putting out 75 watts per channel. The sound was ok not really warm and not that much bass.

Hey man, thanks for your videos. We appreciate you keeping them kinda low key and to the point. Well done. (Meaning not like those tech guys that are nearly shouting all the time). EDIT: I've got an 8800 ready to hit the bench, I bet these two units are very similar.

@VintageAudioFever 4 месяца назад

Hi Jon, thank you for your nice compliment... as far as your sa-8800, very close to being twins those 2 amp...I actually have one on the bench, it's my very own unit, I keep putting it aside as others need work on theirs...my stuff gets seen last. haha!! hopefully soon I can finish the pioneer 8800.

Super, I'll be watching to see if you do work on the 8800. I'm also in no hurry, it's a barn find from a good friend and he's in no hurry.@@VintageAudioFever

15 ohms ESR on a 0.47 uF cap is most certainly not "open". Normal ESR is 7-8 ohms (I just measured one).

@VintageAudioFever 4 месяца назад

Hi Pete, I may have used the word open, I think the better word would of been high/higher than normal, like twice the resistance as it seem. Thanks for clarifying this for me though!!
