Hey all, so for some time the reverb in my Soul O is getting progressively worse. It's currently sounding like a fuzzy echo when the reverb is engaged - I had it looked at and while the tank was fixed back in July, I think it may be the tubes this time. The reverb driver and recovery stages are shared by half a 12AT7 and 12AU7, I have the AT7 and the three AX7's (AU7 is backordered for another week -_-.) Should I wait to retube the preamp section until the AU7 comes in?
Also.. how often do you guys retube the preamp section of your amps? This is the first time I have done it on this particular amp.
I don't change my preamp tubes often unless something seems wrong. They should last a good while, but if you hear noise, try replacing one at a time.
If your retubing because you just want a different sound, then just go for it. I personally wouldn't worry about waiting for the AU7 (but I wouldn't put anything else in there either - a higher gain tube will probably maybe your reverb super loud I think). Or wait if you prefer ;)

I'm mainly retubing because I haven't swapped the preamp section since I've been the owner, wanted a fresh slate with gigs coming up and whatnot.
How long has it been since your amp has had some lovin'? (As in re-tubed, re-biased, etc...)

Retubed it with KT66's back in july, however I'm picking up some Mesa or GT 6L6's and seeing how they sound in there. I remember reading that the speaker got very ice picky though so we'll see, there's an Eminence Legend at work I may try out in there. First time preamp tube retube.
To be honest, I've never had the amp biased. I have a Bias King Pro I am going to try out when biasing it for the 6L6's, the GT was built for user biasing.
