    Can you keep the amp on standby when switching pre tubes?

    I'm not sure if you can damage the amp by doing this, but either way the tubes are heated on standby so they'll be hot to the touch and more prone to damage.

    Fine. No damage to amp. I use a little silicon heat glove (available anywhere kitchen stuff is sold) to save my fingers from being burned.

    I usually turn it on standby and off, but I guess you've read its fine on standby. The preamp tubes don't get as hot the power amp tubes, IME. So testing out different tubes for 10 minutes each, they'll be ok to touch bare-handed.

    I do it all the time. Either flip to standby or turn down the master volume.

    I once fried my fingers doing that.

    They were pretty tasty, though.
