I can't think of a company ---but here in AK we have 2 techs that rebuild Pioneers and both are VERY top notch.
In fact they are so top notch that the wait time for your receiver would be close to 1 year. This is how busy they are --- but they both are very fussy and do the job right.
They are Markthefixer --- and--- Echowars.
Echowars rebuilt 2 Pioneer 1250's for me and they both are masterpieces and the work and attention to detail are stunning.

I reside 3 hours north of Syracuse, NY in Massena, NY 13662. I have previously used Bill Green @ Circle Stereo on my other Pioneer equipment but........I was looking for someone to do a total refurb on my SX1010 including the cabinet, faceplate, sonics etc. I would like to have it in our living room to power my JBL 4311's so it needs to be mint or close to it with the sonics and cosmetics.
My other Pioneer receivers:
Pioneer SX-838
Pioneer SX-750
Pioneer SX-980
Thanks for all your help,
Brian
p.s. Listening to the SX1010 now and the Christmas tunes sound great.
Mattsd did a fantastic job an outstanding job on the refurb of my SX-1010. He kept me updated almost daily with the progress with photos, videos and phone calls of before and afters. I was just simply amazed at the talent.
BUT, when I recieved the 1010 the power supply board was trashed in shipping, Ugh!!!
Matt found a power supply board so I shipped the 1010 back and its finally completed.
Be wary when shipping these beasts!

Well, where do I start now? FedEx dropped my SX-1010 somewhere in the shipping process! This is the second time, once by UPS now by FedEx wiping out the power supply board. As the FedEx driver was walking to my door with the box, he was saying that it had been dropped and damaged during shipping at that he already had put notes stating that on his paperwork. As per Matt we removed the bottom cover and examining the PSB which had a crack or 2 in it. Tried to power it up and the relays kicked in then a snap, crackle and pop then nothing. Relays would not kick back in. Its shot and now I'm petrified to ship it back for repairs. Packing material consisted of bubble wrap and more bubble wrap with shipping foam. Also, a piece of 1/2 piece of plywood was velcro'd to the bottom of the 1010 to prevent any penetration to the bottom cover. The Piece of wood was split in two when the 1010 was unpacked. Must have taken quite a hit!

Wow that really blows.
Thats got to a total PITA for you, sorry to hear it. That 1010 is a beast. I get tired just carrying mine up from the basement. I'd be filing damage claims all over the place.
You might want to try and contact Mike @ Hudson Valley Hifi in Chester. He's a member here. Might be closer than Mattsd (Sorry Matt I don't know where you're located) to the point where you can drive it to him.

Figure it's easier to revive this thread then start new.
Brian's 1010...he found a new PS board and shipped it to me. Replaced caps, transistors, diodes, and zeners. Out of circuit tested resistors and many had drifted way out of spec so replaced. Receiver arrives, opened case and noticed burnt component smell. Removed Matt's board and did not look broken but had odor. Installed new board and started to bring up slow. At 35v R11 starts getting way to warm and begins smoking. Hmm.... Check out Matt's board and r11 is fried.
Brian's described the symptoms as intermittent cutting out of both channels when warm. My initial feeling here are the receiver was going in and out of protection. All other voltages on power supply are dead on. I haven't dug into the schematic deep enough yet but my initial thought was amp board but now I am thinking protection circuit. Or is it possible the new 2073 is no good? Just floating this out there to the Pioneer gods of AK and trying to calm Brian's nerves. Thanks in advance.

once "we" get this unit going, i would like to get the damaged power supplies that have been removed.
i am working on a long term project based on an idea to mod them to make them less vulnerable to that type of damage. a bonus will be to have them runb cooler.
as to advice, no schematics here in hospital. iiac r11 is series resistor (10 ohm?), in which psu line?
remember, it was working until shipped, or when bad psu powered up. thus impact damage in a different area or an overvoltage killed it.

R11 is a series resistor in the 56v leg that goes to pin 14 then to pin 4 of amp board. I will try to post a pic of the PS schematic. It worked for Matt when he did the work, then shipped to Brian which is where the symptoms started. It was battered by FedEx on its way to him so it is very possible something else was damaged.
It is so great to see you posting Mark. I hope you are doing better everyday. As to the other boards I will pass it on to Brian.

When I get home I'm going to swap out r11 and remove the wire from pin 14 on the PS board run my meter from pin 14 to ground and slowly bring up on variac while watching and see if we are still frying the resistor or getting good 56v. If I'm not mistaken that should begin to isolate the problem board.
Thank you Matt, I started looking at the amp board schematic and saw those. Any output trans in needs of swapping during the rebuild? I honestly never even looked back there.

Hey Mark,
Hope everything is coming along. Those PSB's are yours!
I appreciate everyones knowledge and expertise trying to get my 1010 up and running without burning down the house. The lady of the house would not be happy!

I would check them, but I doubt they are bad. They are the original outputs, if I remember right they are Sanken's. It's possible that one or more of them got taken out, but I don't think so, if they had failed when it did the crackle pop like Brian described, there would have been a lot of magic smoke.
not necessarily, do some quick c-e ohms checks while they are in place. dead shorts will be obvious.
the driver stages (q7/q8 & q9/q10) of the amps are (had been) vulnerable to over voltages...
without my records to check, what did i (you) replace them with?
