From the post
A J-FET / MOSFET amp emulator of Krank Krankenstein. Very interesing transistor setup with MOSFET and silicon diodes in some of the gain stages. Schematic specifies KP303s for the J FETS but western analouges is J201 and 2N5457/58. Managed to keep it reasonable small so the brave one could try to fit this 6 knobber in a 1509B box....
MTK demo time.
