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

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..

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...

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?
