Thanks Niek.. I'll try replacing those parts you mentioned. The IN-18s are socketed.. I wouldn't expect to have much trouble moving them to a new clock. I'd hope not, anyway.
MichaelB.. I replaced C6 first, when I was having a problem with all of the tubes lighting up all sorts of numbers like crazy.. and then the fuse finally blew. It was Jonas' suggestion it was C6, and it fixed that particular problem. With the heatsink epoxied to both the voltage regulator and the mosfet, I wrongly assumed it was the voltage regulator getting so hot. (Hard to tell even with a infrared temp probe.) But now that I've removed the heatsink and installed JT's voltage regulator board.. it's obvious it's the mosfet that's cooking. I'll get these parts ordered and we'll see what happens!
