OUCHIES! (also posted to WTB) 
I'm an unhappy camper. I nearly had my 39-116 chassis up to 100%, but tonight it ate it's output transformer.
Was playing beautifully then started crackling. I thought possibly SMD, but no. After a few seconds, it stopped playing, the input current almost tripled, and all the B+ voltages tanked.
First I checked to make sure none of my caps had died. They hadn't.
The output transformer had shorted one side of the primary to chassis (about 100 ohms).
I've verified with a single ended transformer that the radio still plays (odd duck, this one.. without the negative feedback circuit working, the thing will never lower the volume much past deafening).
At any rate, I really need this transformer. So, if anyone has one, you can pretty much name your price.
