Fading signal- need help.
#2

The link you gave is for an A-K set.

As for your problem, and your voltages:

You've either got a gassy tube, or a bad grid leak resistor. You're not seeing 800V or 1000V on that pin, those voltages don't exist in that set. What you're most likely seeing is 800-1000mV (I sometimes make that mistake with DMM's, too). Try swapping out the tube first, then start looking for resistors connected to it that have radically changed value.
