Yes sir. Those receivers are not supposed to run hot. Especially not loaded up. Makes me wonder about the bias setting

Sucks because I really don't trust dudes work lol. He had so many excuse and took him 19 months . Scares me that he rushed it out just to get me off his back...
 
Yep. Email him bout the heat issue. See what he says. I'm real curious.. The Specs are the same design and I've never needed a fan on.mine...have you checked the heat when using the amp section.?

Super hot. Couldn't put my hand on it when I was driving it ..right and left sides get hot as shit to touch top of receiver.
 
I've worked on a couple 850's and a 1050, and they cool runners ...

Unfortunately, I don't believe the SX-1250 is compatible with a low output MC cartridge. You would have to use a step-up transformer to use a low output MC cart with the SX-1250. If it's a high output moving coil cartridge with 2.5 mV you would be OK.

Probably a no go for hooking up a powered sub woofer to your SX-1250.

Can't he use a Radio Shack 42-2109 phono preamp for MC? I still have one, those little boxes are gold in my book

The 626 gets pretty warm just sitting there idling, not abnormally but when I walk into the garage, I get that whiff of Pioneer warmth. I leave it on all the time
 
Jase...can you get a couple pics of the heatsinks? If the 1250 uses the same temp compensation diodes as the rest of that line that could be a problem too. The leads are very brittle and prone to breakage..

That's got an STK module though IIRC.

I get the smell as I did with the 939. But that 939 ran cool. I pushed it hard lee. But It got hot at normal levels also. Just Idling I can barley put my hand on the top on left and right side. The center isn't as hot nor is the back. Just the 2 sides
 
You brought up the bias lee. He said he was having trouble getting the stabilizer board stabilized . So it wouldn't hold bias. But I guess he found 2 diodes wired in series that was messing it up. He said he changed it to the correct one and bias locked in great then...
 
Circuit pro electronics in granger/south bend Indiana .. A dude in a pull barn with more vintage shit then I've ever seen in one place. So I figured he knew his shit..

I don't know the specs of the RS model you have, Ron. I think that model is one used for a receiver or preamp that doesn't have a phono input. You use the auxiliary connections of the receiver or preamp to connect the RS to the turntable.

You could be leaving a lot on the table without matching impedance, output sensitivities of the cartridge to the phono section of your preamp/receiver or stand-alone.

I've heard many good testimonials on the Denon DL-110 cartridge.

Ok, gotcha

Would a line stage preamp work then?
