35 years ago my parents gave me a Pioneer SX-650 for Christmas.

5-years later I flipped it to my sister for $100 because I had acquired a fancy Yamaha amp.

28-years after that asked my sister to buy the SX-650 back...never received a response. 6-months later at Christmas (2-years ago) a minty SX-950 was under my tree, gift from sister who could not locate the old SX-650.

Today out of left-field a SX-5570 was under my tree (celebrated 3-days late for obvious reasons)...again a gift from sister. Apparently when she originally sourced the SX-950 for me she bought herself the SX-5570 but found that she wasn't using it --- so gifted me that one too

Haven't been able to find much info on the SX-5570 but am interested to learn more if anyone has info they'd like to share...

Cheers...

 Seems to be the Euro version of the 950, with the addition of the voltage selector. Cool looking.

 As already mentioned, it's the either the Euro or Asian market version of the SX950. BTW I always thought that the Pioneer SX750 and SX950 were perhaps the best sounding receivers made. And I'm an old Marantz fan!

 That's a baddass looking unit!!!

Had a SX-750 (bought new in 1978) that I "lent" to my sister about 20 years ago.

Never got it back.

I like your sister better than mine!

ENJOY!

 Pop the lid off and take some pictures. I will take pictures of my 850 and we an compare. I bet we find they are the same.

One thing though, the 850 is so overbuilt that with a bigger power transformer it could put out alot more power. It is rated 65/ch but I think with a few minor change it could easily put out twice that. It has four outputs per channel and more heat sink than some 200/ch amps.

 Waiting on some deoxit and when it arrives I will do so.

My understanding is the SX-5570 is equivalent to the SX-950...

 No pictures necessary, it is a 950. I looked it up and noticed it has three sets of speaker outs the 850 only has two.

Tell you this much, even pictures of the inside would not be conclusive because the 850 is so similar. I bet all but about a dozen parts are interchangeable.

So, enjoy the extra (extra ???) 20 watts per channel. Note that I consider these to be among the best receivers Pioneer ever made, and can only be topped by esoteric stuff. Like the MAC 1900, though I think we got more power. Alright there are a few Kenwoods out there... In those actually the 9400 is better than the 9600 because the 9400 doesn't use output ICs. I made some money retrofitting and adapting these things to take an available IC but I am sick of it. The job may work well but it looks like shit.

But you definitely got a rara avis there. I would never sell it for one. Actually I can't really think of anything I would be willing to trade it for. Maybe a really nice gun, but I mean a really nice one.

However when you write your will I can mail you my name and location.

If you ever want to send it to me for service or something, send it naked. Take off the front plate and all the knobs, and the top and bottom covers. I would rather not be responsible for them. In fact that is how my clients usually bring things now anyway. I prefer it

One thing, that thing might be full of 2SC726s. And if needed I have the right kind of FETs for the preamp section. (if I am thinking the right unit here...)

Yes, I have actual JFETs in both polarities.

Anyway, have fun with your bad ass to the bone machine there and don't bring the cops too much.
