Well, if there's no high voltage, obviously there's a problem and the amp can't
produce any output power (without high voltage!).
Is this a "new" amp or a "used" one?
Do you feel comfortable working on high voltage circuits? This obviously takes
a lot of precautions, and some specialized equipment.
If so, first thing I'd determine is if the HV metering circuit is shot or if
there's really no high voltage. HV being "absent" and no fuses blown would
indicate to me that something's "open" (rather than shorted). I'd have no
problem looking for that, but then I've worked on HV stuff all my life. If
you're uncomfortable with that and aren't well aware of all the precautions
that need to be taken, you need help from a local amp guy or the factory.

Amp had HV when hooked up. K3 is driving it. No grid or power. Checked HV
again and it was gone. Fuses OK. Very strange.

Phil, what are you driving it with? How much drive power and what mode?
When you drive it does it indicate any grid current? Plate current? What's
the high voltage meter indicate?

Just received this amp and wondering if ALC must be hooked up as asked in
the manual. I haven't used ALC in years. When I key the Amp, I'm not
getting any power out. Relay is closing. Any one help?
