RE: Shorting (muting) SET amplifier output

I have played with turn on B+ delay. It fixes turn on
thump but will not fix one on turn off. Electronics
(or 2 switches)could be used to turn off power to B+
first. However, that will not fix a potential problem
of power black out. I am thinking about electronics
monitoring incoming AC power and shutting power off
to B+ if a single AC half wave is missing. That would
mean only 8ms delay for B+ turn off.

The amp has tube rectifier and only 2 x 50uF B+ caps.
