Which tube in my 70's Fender Deluxe Reverb...?

    Sure could use a hand, and I can't find what I'm looking for with the search.

    My 70's Fender Deluxe Reverb has an extremely sensitive reverb, in that when I walk in the room or even touch the amp a bit, my reverb gets all splashy and noisy. I'm thinking it's a microphonic tube, but I can't figure out which one to change.

    If I'm looking at the amp from the back, which one of the tubes should I change out to see if that's the problem?

    Thanks for any help.

    V3, third tube from the right is the reverb driver. Try a Mullard CV4024 or an RCA 12AT7 there. I have used both in my DR reissue and they were both great. I am using the CV4024 now.

    Well, I have another question. Seems like I have an extra 12AX7 tube, but I don't have the required 12AT7 that is listed for that slot.

    Can I use this 12AX7 in place of the 12 AT7?

    Thanks again.

    The stage sensitivity is usually the springs crashing, not a tube. I guess old ones are stretched out.

    I would;nt, i think it will make your reverb way too harsh and boingy.
