Janis MKII
This is our completely re designed 6922 tube phono preamp, model Janis MKII. It is housed in an all metal chassis for optimum shielding.
Two versions of Janis MKII are offered.
The first version will have both MM and MC inputs, (selectable) using the superb Lundahl SUT's (Step Up Transformers), complete with 8 step selectable input loading to closely match the cartridge used, see below.
The following Lundahl SUT's are offered. LL1931, LL1933 and LL1941. This will give user selectable gain range of 18, 24 or 38dB usin a mini toggle switch located on the input pcb, depending on the model SUT used. Note, each model SUT will give TWO sets of gain ranges.
For example, SUT model LL1931 can be configured for a gain of either 8 or 16, so this mini toggle switch allows the user to chosse between those two gain settings. This means that a number of different MC cartrdiges can be used for any given model SUT.

Each of these model SUT's are also available in Silver Wire for additoinal cost, see pricing below.
Grounding of the SUT's can also be user fine tuned to match pretty much any system setup using shunts.
The second version is for MM cartridges only which will have a simplified rear panel with no switches, just RCA in and outputs.
We have spent months on this re design and the result is an amazing sonic experience!
The 6922 preamp design uses a combination ultra low noise LSK380 JFET and tube cascode input stage with an Aikido-style output buffer. A solid state CCS (Constant Current Source) is used in the second stage.
The all important power supply is a regulated high voltage B+ and regulated DC filament supplies. The power transformer is our own design and custom made for us, a low noise toroid transformer which is housed inside a shielded metal enclosure.
The chassis is all metal.
This is a no compromise design which will give you hours of amazing vinyl listening pleasure!
Above is the rear panel layout showing the MM/MC input selector switch and the Cartridge load resistor selector.
The load resistor values will change depending on the model SUT and desired gain factor chosen. Shown are resistor values for the model LL1931/LL1933 with a gain factor 8 or 18dB.
