Power Feeds from the Variac

The Tesla coil will need 2 power sources. One variable AC from 0 to 110V for the neon transformer and one fixed 240V AC in to supply the synchronous motor for the spark gap. Both power sources will come from my variac module, obviously the fixed 240V is just taped from the mains feed inside the variac case. The synchronous motor runs at a 110V so the 240V fixed supply runs through a stepdown transformer inside the Tesla coil case. I decided to use 2 IEC female panel connectors to get both power supplies into the Tesla case. They are positioned vertically aligned in one of the perspex sidewalls.

The lower IEC socket connects through a retro looking ceramic terminal block to the EFI/RFI filter and then to the neon transformer.

The hole required for each IEC socket was rectangular with rounded corners and was achieved by drilling four 8mm holes in a rectangle and then using a coping saw to saw from one hole to the next.

Have yet to wire up the top socket which will supply 240V to the stepdown transformer for the synchronous motor.
