Hi, I recently purchased a MESA Rect-o-verb Version 1 off of eBay and would like to change the tubes in it since I don't know how old they are. The amp sounds good, so the tubes probably don't need replacing, but just in case ...
Anyway, the power tubes are 6L6 GC STR 420 ... when I went to the MESA Yahoo! store, all they had were 6L6 GC STR 430, 6L6 GC STR-427 Chinese, and 6L6 GC STR-454. Are these the same tubes or do I specifically need to find the 420 ones?
The preamp tubes are MESA STR 12AX7-A. At the MESA Yahoo! store, there are 12AX7-A ECC83 Sovtek Russian 2, STR SPAX7-A, and 12AT7.
I'm thinking I need to get the 6L6 GC STR 420 and the STR 12AX7-A (but not sure where to find these), or maybe the 6L6 GC STR 430 and the 12AX7 Sovtek ones.
And then, of course, there's the whole debate on which tubes are best, so should I even replace the current tubes with MESA tubes? I know the amp does not have to and cannot be biased, and since this is version 1, there's no tube selector switch on the back, so I'm kind of limited to what tubes I can use. I like the sound I'm getting out of the amp, so I'm really not interested in experimenting with tone ... just want to find the right tubes.
Thanks a bunch!
