    Hi all~~ I'm going to need tubes for my new, 1953 Gibson GA40 T combo, it's been ages since I've needed octals. I'm not at all concerned about period correct metal 6SJ & 6SN7's, or coke bottle 5V or 5U4 rect. I want strong, reliable & quiet. Glass or Metal? Without furthur breaking an already broken piggy bank, where's the place to go for these oddball octals? I'll just go EH or JJ for the 3 6V6's, one for the tremolo, but the others I'm just not in the loop.

    Thanks for everyone sharing your expertise.

    The safest bet is to go new-old-stock from a reputable tube vendor. The octal preamp tubes can be microphonic, so screening them is important.

    ^ This. You can easily spend as much or more trying to find one that isn’t noisy or microphonic as you would buying one from a reputable source that’s been tested and screened.

    When buying metal or glass octal tubes I usually plan to buy extras, because even “good” ones from a dealer might be unusable or microphonic in some amps, but fine in others... or only ok in one circuit position, but bad elsewhere.

    I think I have some octals that I bought for a GA-19RVT that I no longer have. They're early 60s RCA grayplates. Actually, I know I have them, I just have to find them. I'll poke around over the weekend and try and find them.
