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 2A3/300B Power Amplifier We are now offering the Kit1 as a pure high gain power amplifier. The kit looks identical to the Kit1 except there are no holes on the front for volume pot or selector switch. The unit has the same circuitry as the kit1 with the volume pot bypassed between the front 6SN7 stage and the 5687 driver stage. The input sensitivity of the amplifier is in the 600mv range and is ideal for speakers in the 90-98db range. Price is $100 less than the Integrated Amplifier version.
