I think I have askedd this before at some point but Im not sure where.
Can I remove the reverb tank from my amp and replace it with a different electronic reverb or some other effect, the reverb sound in this amp is weak which is the reason I want to do this.
Is there anything special about the signal being fed into the tank? And is there a way to boost the amount of reverb without changing the tank?
Thanks

We'd have to see the schematic.
If you carefully open your tank, it should be some springs in there. Make sure none of the springs are loose, and that they are nice and tight. Since you get reverb, it is more likely that there is something wrong with the mecanical part of the reverb and not the electronics. It could also be worth a try to add some sort of booster between the tank and the rewerb, to amplify the signal and make the springs vibrate more.
Whatever you do, don't change your reverbtank for an electronical reverb. Then you're better of getting a new reverbtank.
In my experience most tanks need something around 1/2 watts(depends on the tank) to push them well. Then make sure you have a good enough recovery gain stage to re-inject the 'verb.
True, the reverbs need a decent drive signal. Also, sometimes the reverb is driven so that the output current is "sampled" and fed back to the driver stage - this affects it's output impedance. The tank should not affect the reverb as much as you'd first think (unless it's broken of course): I have heard a very good sounding reverb coming from a two-spring, 5" unit driven by NE5532. If you just have a plain 500 mW transistor as a driver you can pretty much bet that any unit will sound crappy. You might want to check out these links.

so carefully check the springs to make sure that they are tight and if its still weak placce a booster between the amp and the reverb tank input.
If I placec a booster thought will it make the amp louder when reverb in dialed in?
