>> I copied this from an erlier mail. I am currently working with a
>> YC-156, and I have the original 3CPX5000A7 Eimac product sheet.
>> It says warmup time minimum 6 min. without RF AND PLATE voltage.
>> No RF, We never do that, but no plate HV, That's new to me.
>> Any comments, other information or expiriences ??
>That is true, Vern.Also it is highly recommended that the blower continue
>operation for several minutes after shut-down. Eimac also recommends
>only one heater on/off cycle per day for maximum tube life.
>The good news that with only 225 watts being drawn from the heater, the
>amp can be left in standby for a week-end without hurting your wallet like
>most big tubes do.
thanks to instant warmup, big tubes with a filament-type /
thoriated-tungsten cathode draw zero watts in standby.
