I have 2 pairs of gyrator boards for sale. They are fully functional ( I tested all of them in a 6e5p driver at 200 Vpeak to peak) and stuffed with my best selection of components:

Gyrator PCB Update – Rev07
The gyrator PCB has been updated to fit now a wider variety of lower enhancement MOSFETs with low capacitance and high transconductance. The best examples are the BSH111BK and BSN20BK which are great options for currents above 25mA:
The board offers now all the flexibility needed in terms of different TO-92 and SOT-23 package pin-outs to use whatever FET you want.
