Kit LNDVerb
The LNDVerb kit is based on a classic Fender reverb circuit, but uses LND 150 Mosfets instead of tubes. These can be operated at voltages as high as 500 V, to get as close as possible to the characteristics of real tubes.
The kit can be integrated into an existing amplifier or can be build as standalone unit like the Fender tube reverb.
The unit needs less than 10 mA current, so a VPump for example can be used as power supply in a standalone build. If it gets integrated into an existing amplifier the already present power supply of the amp can be used to supply the needed voltage for the unit without the need to upgrade the power transformer.
A reverb transformer of the type 125A20B or similar and a reverb tank are necessary to operate the LNDVerb. These are both not included in the kit.
The needed RCA phone sockets and potentiometers are included in the kit.
Further informations and examples of the finished unit can be found in the PDF below.
Matching parts are linked below and can be ordered with the unit if needed.

- Mario M., 08/11/2021Very good kit. Installed in 5E3 Deluxe clone deliver rich reverb sound and no noise. The installation requires some adjustements to left the dry sound untouched. sound untouched.
go to post - jim o., 09/16/2020Super project, superb support and outstanding tone. I've installed "inside" my Dumbleator (also from Tube-town) with a large 2 spring and it gives that great "boing" i was after (the Slow Dancing big splash tone). I did have a problem with the transformer, (not included) but it was resolved by Dirk really quickly that great "boing" i was after (the Slow Dancing big splash tone).

go to post - Ilya K., 09/03/2020i encountered a problem, when i cannot cut all of reverb with mix knob, if it is wired as balance pot (like it was in reverb units), there's still a lot of reverb with knob all the way down, only dwell knob works or fender AB763 reverb arrangement, where you can wire mix pot to bleed all reverb to ground. balance wiring doesn't come close to 100% signal on either side for some reason, maybe i did something wrong. kit is a good option anyway lot of reverb with knob all the way down, only dwell knob works or fender AB763 reverb arrangement, where you can wire mix pot to bleed all reverb to ground. balance wiring doesn't come close to 100% signal on either side for some reason, maybe i did something wrong. kit is a good option anyway

R52 = 1M, R13 = 220k. Dwell pot replaced with 220k resistor, one end to ground, one end tied to both of the remaining terminals. Use input B, take signal from wiper of the AO-28 tone knob wiper.
Then on, the mix knob did not work as stock. So I rewired it as regular voltage divider: input ("top") from "mixin1", wiper back to "mixin2" via 220k resistor, output from the whole spring reverb back to 12BH7 pin 7 (where the wire from the wiper went originally).
I used some 60 cm long shielded 2-conductor (ie. 2 + shield) wire from the unit to bottom of the organ, where I mounted the control pot on a small L bracket.
Sounds wonderful, and the levels are just right!
