There isnt really much need for a standby on amps that use a GZ34 as a rectifier.

The valve rectifier itself takes time to warm up so it doesnt put too much current onto the output valves until they are also warm enough to cope with it, think of it as a soft start!
 Actually standby switches on such amps tend to do more harm than good because they put such a sudden rush of power onto the valves.

Never played a creme brulee but ive heard good things about them and yes it is the ef86 side of the dc-30 with less power, my dc-30 is blooody loud so less power is a handy thing
