    Hey all,
    I have a 5E3 Deluxe chassis I want to repurpose. Unfortunately, it only has 2 preamp tube holes and I need a third. Is it too close to the others if I situate it in between the two already there? That would give me 1.25" center-to-center. Or, could I use an octal to noval conversion plate and use the unneeded octal tube hole (I only need 2 octal holes)?
    For reference I'm building a clone of the single-ended Supro 6422, with reverb, but sans tremolo.
    Thanks, y'all!

    Hi junior Little,

    1"1/4 = 31.75mm, I don't find that especially schocking if these are tube preamps in following stages order.

    Would you post a picture of your chassis, so we can see what you are planning to do ? ;)

    The V2 slot will be the reverb driver and the V3 will be the reverb recovery and another gain stage.

    I have one of those little Airlines, I bought in the 60's, and I still play through regularly. Too bad they don't still make the little cardboard reverb tank!

    That's sweet Bill! The reason Uncle Doug went with the Fender-ized reverb is due to "reports" that the original sounded rather thin.
    I've built this amp before with the trem and put it in a Princeton Reverb chassis and cab. The thing was amazing, so I'm gonna build me another.
    And, after looking at the 9-pin spacing, I think I'm going to give it a go. I just didn't want to muck-up an otherwise good 5E3 chassis only to find the tubes were too close.

    You won't get Dick Dale surf from the little tank, but I'm surprised at how good it does sound!
