Changing tube in my ABM300 head

Recommended Posts

My new pre-amp tube should arrive tomorrow. Is it as simple as opening up the head (already done), pulling the old one out, and place the new one in (handling it with a cloth to avoid skin-oil transfer)?

Cheers

Whoops I must have been doing it wrong then; I've changed a few preamp valves and can't say I've ever been quite that precious. I've had valves in preamps that I've changed out of curiosity and they've worked fine (for years) after a cloth free change. I may be wrong (and I won't take offence if I'm corrected) but the valve case is just glass, we aren't talking halogen etc. so I'm at a loss as to why you should use a cloth :)

In response to Kurt, I'm putting in a Groove Tubes GT 12AX7-m!

And Warwickhunt, I was told that oils from your skin can shorten the life of the valves. I don't particularly see why either, preamp valves don't get all that hot do they? No harm in doing so just to be sure though.

Got the new tube in.... actually gives less overdrive than the stock one (it was a Sovtek) but sounds a bit more natural. I'm liking it

Hey there, I just put a GT ECC83 in my ABM500. I'm gigging it tonight, so I';ll let you know how it is.

Peace
