    After two years I finally tried to fix the reverb in my amp. I found that the springs in the reverb tank were floating around and are not attached to the center piece. Can I fix this or do I need a new reverb tank?

    1. do you have the sound of reverb in your amp?
    2. If you dont, what do you mean your springs are "floating around". I dont get that.. are they hanging out of the pan broken? Or are they suspended within the pan? Or is the pan with the springs suspended within, just not screwed down to the bottom of the wood cab?

    The springs were disconnected/unclipped. One of them was pretty much almost out of the tank itself.

    Springs should only be attached at each end, at the piezo transducers, which are basically phono cartridges. The center "thing" should be a guide to keep the strings from flopping around, and the strings shouldn't be tied to it.

    I took the springs off completely since they were not connected to the piezo transducers. Can I just put em back on or solder them or do I need a new tank?

    They should just hook on. If they were soldered on before, try soldering them back on. Even if it doesn't work out, new tanks aren't too pricey. Just make sure to get the right one. Part number should be on your present tank.

    If the transducer and its connect to the jack is not damaged, then you should be able to easily connect the springs back into place. Understanding that the springs cannot be damaged and stretched. A brand new upgraded pan is not that expensive btw.. and if you can, get a pre asian factory accutronics. otherwise use a mod pan, which is the most durable repro made at this time.

    The springs attach like a strat trem. There should be some small eyelets in the tank were the springs hook into. Sometimes they break though.

    @Ricochet @TV the Wired Turtle check it out y’all. I must admit I’m a newbie to ever tinkering with my gear hence the lack of proper terminology and knowledge of the parts

    That's toast. The piezo transducer has come apart. I'd suspect the amp took on heck of a fall. The only thing to do is to replace the tank.

    Although I have heard of old Sears Roebuck type amps having piezo transducers, those in current (and most old) tanks are electromagnetic. They are still fragile though!

    Don’t forget to match the 7-character code printed or punched on the tank. The second and third characters are probably the most important as they refer to the input and output impedances.

    a few years back I would gig alot in the Los Angeles backyard scene..sometimes the circle pit would get out of hand and people would knock over our gear, one time chipping our singers tooth lol. That must've been the culprit. kinda glad I've graduated from those gigs..thank for the help guys. Gonna get myself a new tank!
