    :confused:I recently bought a used Fender Tube Reverb R.I.
    It seems to work fine but I noticed it has two 12ax7's in it rather than the
    12AT7 and 7025, called for in the tube chart.
    Should I worry about it or not ???:?:

    No need to worry per se.

    However, it's not correct.
    A 12ax7 in V1 is fine.
    A 12at7 in V2 is how it was designed.
    You can also change the big' 'un to a 6k6 which was the design intention too. Find a good oldie somewhere.

    I'd put the "correct" tubes in. Might make a difference, might not.
    You always want to have extra tubes on hand anyway.

    Yeah, put the correct tubes in it.

    I agree on putting a 6K6 in as well for the reverb driver.

    Thanks to everyone. Now another odd thing I found, [not the ones out of the reverb unit]a tube that is marked
    12AX7 AND 7025......what's with that?

    Same thing. 7025 was a low noise version of 12AX7.
