[Amps] HV relay

[MIKE DURKIN]

Well Jim,

Im changing my 2 at 3-500Z amp to a single GS-35B and in the spec's for the tube it states that the warm-up time is Aprox~ 2 minute. So instead of using  a power SCR in the mains to switch on the HV bank( and probably darn slow to disengage if a fault occurs) I would like to use a Vac relay - probably close to the Plate choke since i have room in that compartment and a delay circuit is darn easy to DIY.

What would you use an anode HV switch for?
