MOD 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.

4 tubes, matched as quad

JJ 6V6 Double Mica double-layered mica in the upper part of the tube. This stabilizes the tube system and significantly reduces possible vibrations that can occur due to heavy mechanical stress. This version of the JJ 6V6 was specifically designed for use in combo amplifiers.

The JJ6V6 is a beam power pentode with octal base and a maximum plate dissipation of 14W. It has fat low end and full mid tones with very good tone separation and a smooth, clean high end - in general, a very balanced tone.
Currently, the only new production 6V6 which is approved for up to 500V anode voltage in pentode operation.

Were raw force reigns...

the sound technicians are at work and do not have the time to handle cables with tender love and care. This robust cable is especially intended for speakers and satifies all special technical demands. The oxygen-free copper strand provides better sound and more durability.
All PVC-versions are easy to wind. Versions SP215 and SP225 are now available with highly flexible 0.15 mm copper stranding!
New are the versions in FRNC and E30 (IEC 228, IEC 332-/1, IEC 332-3 Cat C, IEC 60331, IEC 61034-1/2, IEC 60754-2)

THE ADVANTAGES:

• Flexible and easily windable
• Small diameter
• Great durability through the use of a special jacket mixture

The ET90 is our lastest addition to the ET65 lineage.  Taking its core sound from the ET65, the ET90 gives you more all the way around.  We went to larger motor and a beefier voice coil on this model.  The result is more headroom, more power handling and a bigger feel.  If you've been looking for classic British tone with an "open" feel and a lot of power, the ET90 is your new favorite.
