I have a Magnum Dynalab 90T FM radio which has one 6922 valve in it.

Given the 10,000 hour life of the valve, should I leave it switched on all
the time ? (stops drift)

Yes...is the answer....ACtually valves last longer when left on. They
usually fail during turn on transients, after being cold......

** 10,000 hours is only 11% more than 1 year.

Either fit a " standby switch " to disable the HT, like guitar amps
e - or fit a 15W, 240 volt pilot lamp inside to replace the heat
generated by the valves when the set is off.
