So i have had an ebay search for reverb tanks for quite some time and wanted a stand alone reverb to test them with. I have taken the supro reverb, premier90, lamington reverb and other designs i could find to copy from and did some design by soldering iron. The chassis is an old philips sine generator as this is a wonderfull chassis for point to point as is and comes with a very nice power transformer, tubes, knobs and what not and is cheap as dirt. The schematic is almost finished, the high pass in the reverb driver still needs more base but this unit is most of i wished for. It is not a 6G15 and it does not have a turret board but it does have some other benefits up it's sleeve. I aimed for not driving the reverb tank too hard and for getting the most out of it without having tank artifacts, hum or hiss. I have learned a lot in the process of building this and most of it is taken from this board. So i would like to share this with you guys.

Well, reverb is what you want it to be in the first place, but i am still very happy with this circuit. I think this is coming from separating.
1: An unaltered dry path
2: a reverb driving stage (or two)
3: a recovery stage
4: a mixer
Each adjustable without altering another component.
This is giving a good point to add effects, too. Putting my cheap delay between the reverb and the amp sounds very nice and even better than in front of the reverb. I always wanted to put the reverb behind the preamp like in a Deluxe Reverb and this never worked out, except for when dialing it in precisely. And it never did what i wanted. And this does so much more. i have a lot of resistance in the reverb path and the dry path, too, but i think it is totaly worth it.

Very cool!
The chassis caught my eye as it is very similar to an old Heathkit signal generator I have, and don't use much. Hmmm . . .

I was so happy with this that all i wanted was another one.
