I closed the cage and put all the tools away. I am crestfallen.

Yes, those resistors measured 300% off. So, all of you that THINK they have set the bias so and so, better check those resistors!!

Well, after many years, I was happy to think that I was at the root of the problem and the solution. I replaced all the cathode bias resistors, too.

I patched up the bad solder connection and tried out my new soldering iron. Everythink seems to have gone like clockwork: I am actually getting better at it, I thought!

Nothing. Nada. Eventually, I noticed the flash of the fuse. I went through four fuses thinking it was the fuses that were bad!

Well, no CA-CHUNK. Hardly anything. I, at least, like a fireworks display once in a while ;-)

I am thinking that the power supply is dead and shorted somewhere. I may have dropped something, but I am usually careful. It is a vertical board, so it is hard to drop things that don't just fall through.

So, I was expecting the ca-chunk of the transformers as they charge the caps, but it never gets that far. Hardly a wimper. I'm perplexed?
