These are lower gain versions of the 12AX7 and can make quite a difference. V1 is most important as that is your primary gain stage. The third 12AX7 is your Phase Inverter and has minimal impact on the gain/tone. You can even try just removing the 12AX7 from V2. The amp will still work fine, but may have a bit more clean headroom.
Good Luck............. |
Nice info, thanks Russ.
Ok just took a better look at the amp. So I found a pencil in it, oops!! This seemed to be the major vibration happening.
It's still quite farty when turned up, to my ear, it seems to be coming from the speaker. I can't see any visible problems with the speaker itself, but I dont really know what I'm looking for.
I'll try the tube thing, and look around for a new speaker and then repost again. Thanks!!
