A pal at work gave me the reverb tank from his eighties Marshall head!
Wading through reverb threads is a little daunting on the Search function. sooo...
Can anyone recommend a tried-and-true simple solution to adding reverb to my board? I'm thinking mosfet or transistor powered if possible. I'm not much of a craftsman.
My Seventies Bassman 10 sorely needs to get WET!
Okay, now I found the GGG circuit and the Accutronics website!
Appears I have a model 8 3-spring tank. Not bad!
Is the Center Stage suitable to build with this tank?
The only #s on it are 3 B (90-2.2K)
Thanks!
Adding reverb to a no-reverb tube amp is a MAJOR modification. Essentially you jam the works of a Champ Amp in there. A power bottle and transformer to drive the spring, a dual triode to recover the spring sound and mix it with the dry sound.
I would not do this to a Bassman 10.
Get one of those $69 reverb pedals. Yeah, digi-reverb is not the same, but some of them are very good. And a lot less butchering on a fine nearly vintage amp.
... or you could build a reverb tank to place on top of your amp! Lots of schems out there with good amps for reverb tanks.
Wrestling tanks into amps takes hardware and there are many requirements.
Hafta admit that after doing it a couple times, well trying to, I ended up with a rather large tube-reverb, and a Holy Grail that was and is a very quick fit.
Since reverb sounds good last, a couple jackwires [and power supply] spliced it quickly and invisibly into the combo amp, to the side wall under the input.
I can tell a difference of course, the HG is lower noise, the tube/tank sounds a bit more like a T/T reverb, mostly just a little different in sound, from ''days'' to ''not possible'' different in installation difficulties and requirements.
The Accu-site shows what the input/output impedances are [I believe I have the only one made that doesn't have the usual marks on it], driving the input transducer [for a long, 2 or 3 springer tank] takes an amp with some 'uumph'.
I used this project to drive a reverb tank, the version in figure 3.http://sound.westhost.com/project34.htm (http://sound.westhost.com/project34.htm)
I tried the Stage Center but never got it to work to my satisfaction, maybe because I didn't have the right tank. The Westhost version doesn't have as many options as the Stage Center but works well with the Accutronics tank I got (a 3 spring tank for a Marshall) to give a nice reverb.
After pondering the same question as the OP (solid state spring reverb pedal), I decided to go with the G. Forrest Cook reverb. It's got a layout, good documentation, and a dwell knob. On the down side, it's not as popular as the Stage Center, so there's less help available. I bought a PCB from John Lyons and all my bits and pieces from Smallbear, then went ahead and built something else. This is my next project, though, and there's a thread for it (see below) with links, some transistor questions, and my BOM. Good luck.

NO NO NO!!
I would NEVER butcher my Fender--I'll buy a Super if that is what I want.
I had been eyeing that GGG verb kit before I got this tank, and it is pretty much what I want: Switchable spring sounding reverb on the pedalboard.
Thanks for the recommendations, and I'll be following that thread.
Maybe I'll just flip that tank on the 'bay and buy the GGG kit!
