Accutronics Reverb Tank 4AB3C1B

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.
