Thanks, Ray, I didn't realize the rectifier tube....

....heats up more slowly than the others...

or maybe it's that even though it heats up at the same rate, the B+ comes on softly, so cathode stripping doesn't occur anyway...

in either case, I see now - yeah, you're right, I don't need the delay.

Well, how about that - Heathkit knew what they were doing after all!!

Another great reason to use tube diodes, sure saves a lot of trouble. And gives better sonics. Well worth the voltage drop and filament current, I think.

Thanks for the caution about the cathode ending up at B+, good reminder.

best, charles
