Advanced Self-Resonant Driver Board
The advanced self-resonant driver board (formerly known as the PSSTC board), is a complete driver control board for the First Generation DRSSTC system that utlizes secondary base feedback. It features several examples of how fault detection circuitry can be used within a DRSSTC system.

60kV, 50MHz High Voltage Divider
This schematic is for the design of a fully compensated 1000:1 60kV high voltage divider with a working bandwidth of 50MHz. High frequency response of this high voltage divider is flat out to approximately 50MHz. Please note that once constructed and potted, you will need to recompensate the divider to achieve its proper bandwidth.

4kV, 38mA Mini Tesla Coil
This schematic is for a mini spark gap Tesla coil which uses an open frame 4kV 20mA Franceformer NST which has been modified for 38mA (50% of internal shunts removed). This coil has produced up to 14" of output arc. Please note that Franceformer no longer makes a 4kV, 20mA open frame NST. I believe they might make a 6kV, 30mA version though.

Stacatto Controller for Vacuum Tube Tesla Coils (VTTC)
The Stacatto Controller is a very popular add-on board for VTTCs that allow one to vary the BPS of the VTTC by pulsing the cathode of the vacuum tube ON and OFF. This controller provides true AC 60Hz zero crossing synchronization as well as a burst mode option. Great for a variety of effects with VTTCs.
