    Bugera 12AX7 Tube Suffix Meaning? Anyone?

    Hi. So can anyone explain Bugera's 12AX7 suffix system?
    From what I can gather the 12AX7A is the least noisiest, and is ideal for clean channels (V1 tube slot). At least that's where they always are found. From there the noise level may go up a bit but overall output/gain is a bit higher and this continues all the way to 12AX7D. BUT, that's only what I think to be true. Can anyone confirm or clarify this?

    What brand of tubes are you talking about? Are they actually branded bugera?

    There is a plethora of tubes on the market with different characteristics. Ive found that keeping a selection of different tubes in the drawer, trying different combinations, is what works best for me in the end.

    Hi. Robert. I'm referring to the Bugera branded tubes. So far I've seen 12AX7's from A to D. I have four Bugera Amps and the 12AX7A's are in the V1 (Their best?) 12AX7B/C in gain and P/I positions. Most interesting is finding a 12AX7D in a VT999 Tube Monster pedal.
