Spring reverb amplifier circuits

Man, I missed the boat when they had these as kits for sale. Now their prebuilt units are going for 300-400 bucks. Ugh!
The first kits were all through hole components and looked pretty straightforward to build, then they offered an assembled board of mostly SMD components. I like the one JM posted for the tank driver circuit, and it wouldn't be hard to put together a decent preamp and recovery stage using either op amps or jfets.
 
Hi Kay, I'm dreaming of a Frankenstein stereo hi-fi system with 2 tanks, one for each channel. Did you ever find the circuitry you were after? I'm still looking.

I'm too new to diyA to send you a private message. Feel free to respond here or take it offline.

Thanks,
