Want to build preamp-eq pedal for rack reverb

Okay so I am in desperate need of a spring reverb for my studio. I have a perfect working tank in my Laney VC-30 but something is wrong with the reverb circuit and it never works. So ideally I would like to take the tank out and have it mounted in my rack. But now I need a preamp/eq/return preamp pedal with RCA outs to power this thing. Can anyone point me in the right direction on this. I've seen the video where the guy builds one with phono preamps and alittle power supply, but an all in one contained pedal besides the actual tank would be ideal. Any leads?

What's the input impedance of the tank? They vary from 8 ohms to ~ 2K, and that will play a role in getting something that drives it well.

In terms of an off the shelf solution I have no idea, but the individual pieces are quite simple. A headphone amplifier will usually get you the drive (or a small amp, I'm fond of single ended tubes pushing springs), recovery is usually close to a typical guitar level signal, so loads of stuff can be used there..
