Interstage Mono Blocks

The unique design style makes use of an interstage transformer on each channel - rather than having an additional tube driver stage, the interstage transformer takes over this task for ultimate authority!

The power supply and driver circuitry is all hardwired and the user has a choice of components. The power supply supports large black gate or Jensen Electrolytics that protrude through the chassis. The mechanical design of the unit is second to none using all stainless steel metric hardeware; countersunk screws and removable plates make for a truly fun build experience!

Then there is the all-important sound - In combination with an AudioNote M3 transformer coupled pre-amp the interstage Mono Block provides a level or realism and detail that you may not have ever experienced.

Kit1 300B/2A3

The Kit1 offers you the chance to experience real high quality S.E.T. (Single-Ended Triode) amplification for yourself - but at a highly affordable price. This kit has been evolving since it first appeared in the mid 1990's and, as such, has proved its high reliability and customer satisfaction index time and time again.

The Kit1 300B/2A3 is available in many different configurations including Hi-B Double C-Core output transformers, Integrated or Power-only models, etc.

This kit now comes configurable for either 300B or 2A3 operation. You simply specify which tubes you wish to be supplied with when ordering. We supply one pair but the kit can always be modified for either tube with about 10 minutes of soldering.

L4 Series EL34 Power Amplifier

This is a very rugged EL34 Based Tube Power Amplifier operating in Class AB1. We are squeezing 35W of pure smooth and warm EL34 wattage out of this unit.

The driver section for each channel consists of an ECF80 tube. This part of the amplifier (the driver stage) is a high quality thick PCB with highest grade copper tracks - The feedback and compensation circuitry is on this board - and makes for a straightforward build!

The power supply uses a huge Mains transformer and choke along with some ultra fast diodes to supply the AC filaments to the driver and power tubes. An optional Mundorf M-Cap can be simply connected to the circuit as an optional high qulaity upgrade (or you can buy your own and add it at a later date if you wish).
