    Anyone got any experience on these? I've just had my bassman 135 revalved with them and it now sounds great in my opinion. Anyone else like them or got any stories or info about them? the tech that repaired my amp put them in himself and they replaced very old set of mazdas.

    I retubed a Mesa-Boogie Bass 400 I used to have with Ruby 6550s. They performed well--sounded good, held up, didn't rattle--but I kinda wish I had gone for Svetlanas instead. The Svetlana 6L6/5881s I put in my guitar amp sounded way better than the other tubes (Mesa, Groove Tube, Sovtek) I had in that amp. AFAIK all the Rubys are Chinese and at least at the time I got them Russian tubes tended to be better quality. I've since gotten rid of all my tube gear (except my Eden WT-400, which has a preamp tube) and to tell the truth, I don't miss it.
