I have a reverb tank that I know where it came from (Hammond Organ)

what I don't know is whether it works- the Hammond had already been cannabalized before I got to it

springs are in tact - how do I test it to see if it's any good?

run a low AC voltage into the input (or doe sthat matter) and see if I get some similar voltage on the output?

I'd like to build a stand alone tube reverb unit (I also have a Hammond AO-44 reverb amp which came from another Hammond that was working and was being parted out.... It will probably require some slight rework to get it to be functional for my desired use... but i need to know if the tank works before I get much farther along!

Just plug the output into a guitar amp, and thump the case with a finger. If the output transducer is alive, you get the sploing. I have almost never heard of a spring tank's driver dying- but you could test it with any line-level signal source, most likely. Drive its input with your Ipod or whatever, and see how sproingy the output sounds!

to make sure I understand this

So I plug the output from a preamp into the input of the tank and run the output into my guitar amp?

Yup- it's line-level in and instrument-level out, usually.

I use a spring reverb with my mixer. The output needs lots of gain, you can use a guitar amp or make some sort of driver, or if you have a few extra channels, you can just use the mixer.

plug a fx send into the input on the verb. Plug the output of the verb into a spare channel and crank the gain almost full. Take a pre-fader direct out (or an insert out) from that channel and plug it back into another channel and adjust the gain - this is your FX return. You are stacking gain stages here. 2 channels worth of gain is enough, but I guess you could use more. The most awesome thing here is that you can dial in feedback - from the return channel fx send back into the spring reverb (be careful) a little bit goes a long way.

It sounds great. I only wish I had more desk space in my current setup so I could be doing this all the time. Smile

Google around for "Shitty is Pretty: The anatomy of a funk 45"
you want part 2. Gabriel Roth goes over this in that article. I can only seem to find part 1. Sad

All the links for part 2 are dead.

anywhere an oddball tank can be repaired. You know, those wires that are about the thickness of a hair.
