This is also posted in my original thread about a high pitched sqealing with the lonestar special, (modern era amps 1991 - present) but I thought I should post here also.........
Well.... I just bought a set of five JJ tesla 12ax7 s.
This is the type I bought for my F30 when I had a similar problem, (although the symptoms were not the same) they seem to work well, and was a vast improvement over the sound of the F30. I went to the eurotube website and read up on the ones they sell etc. and the different designs.....also I read about jj electronics and they seem to be in the know as far as making quality tubes.
I don't really understand what they mean when they are talking tubes running 'hot' or 'cold' as far as how it relates to bias etc. (actually I dont really understand what bias / fixed bias is) and what the difference is ....
funny thing the F30 had "russian #2" mesa 12ax7 s, and the lonestar had "chinese #1" s just by ignorant hearsay, I would expect that the russian variety would be a better tube......if that's the case, then why would they put a 'lesser' tube in a higher quality / cost amplifier??
anyone have any experience with these jj tesla tube in a lonestar special specifically ??
Thanks again in advance you guys.
