That sounds like it could possibly be a blown fuse.
You certainly must have checked in your trouble shooting, but I threw that out there just in case.

Quick on/off on anything using tubes is not a good idea.

As Theivin'Heathen says, a fuse is most likely.
Once the heaters are up & running & the amp is hot, there's not much danger of damaging anything significant by turning off & on quickly. Fuses may not like the surge.
As well as the externally accessible AC fuse the amp may have an internal fuse inside the chassis. Don't attempt to change either with the amp plugged into the wall. Unplug it when changing the external fuse & drain the filter caps before attempting any work with the amp's chassis cover removed.
Replace fuses with same type (slo-blo, fast blo) & rating in A/mA. Don't try and be smart by fitting higher rated fuses, just be a bit more patient when turning off/on...say 30s between power & standby to on (you don't need several whole minutes with 6V6 & 6L6, only with very large tubes like KT88, 6550, KT120 etc), about the same from play to standby, then power off.
