    A friend of mine would like to re-tube her Gibson Falcon. It has three 6eu7 tubes in it. She's short on cash and they seem to be a bit on the pricey side.

    I was wondering if there is another tube that can be substituted for the 6eu7 that is less expensive with out having to do any mods to the amp?

    Thanks!

    No, but I believe SovTek has a cheaper version. I would spend the few extra $$ and get some RCA's from a reputable tube dealer. These will last much longer and sound much better.

    Seem to remember you can rewire them for 12ax7. the pins layout is similar jsu a few need to be swaped....a good tech can do it ...but cheap to just pay for them

    You can sub a 12AX7 for a 6EU7...the overall tone and gain are similar and a 12AX7 is actually a little less noisy however there are lots of good NOS 6EU7s out there and they will last quite along time.

    You can't sub a 12AX7 in for a 6EU7, the socket is wired differently. Good 6EU7s aren't that hard to find and pretty reasonably priced.

    You can get NOS 6EU7s for $10-$15. They're plentiful, too. :confused:

    No. You can't directly sub 12AX7. You can rewire the socket and THEN sub.

    6EU7 is basically identical to a low noise AX7 but with a different pinout.

    NOS 6EU7s are half, or less, the price of NOS 12AX7s. A great deal!

    Is anyone aware of an adaptor you could use to make a 12AX7 socket compatible with a 6EU7? Or maybe where you could get parts to make something like that?

    you can find the parts at antique electronic supply. You need a 9 pin female plug and a 9 pin socket.

    I hate bumping old topics, but stumbled onto this one. BUT, yes I have made an adapter with the 9 pin socket saver. Mine was for a 7199 sub. worked like a charm

    Just search ebay for 6EU7, they're down to around $15, buy it now, NOS.
