Tough day on the eastern front.
I have been listening to Gunevere dispite the fact I have more noise then I should. so today I thought I would try to track it down. most of it is 120hz and I am geting that hum that riseis with volume but stops at max. Might be a little grid current flowing, I am not sure yet. so I thought before I drag out the scope. lets check the grounds and put some grid stoppers in. so I did.
Now I have a lot of hum.
As I have some new CDs I wanted to listen to I put the Nickel wonder back in. All was well for a while, then the music stopped. A quick look, no glow. Bummer I must have lost the filement supply.
Poped the top of the power supply, smoke, black acid dead transformer smoke.
Seams with all the shifting, the drain wire of the interconnect broke free and shorted the 6V. I swear that transformer was cursed.
But don't worry the fuse surived with out a scratch...John
