Re: Please Does Anyone Have A Terry Filter?

The resistors can usually be found at surplus parts stores (1 to 5 kohms power resistors) and the capacitors can be salvaged from old tv's, doorknob capacitors (500 pf). For connectors I use 5 way binding posts. You can mount this on acrylic or perf board. I've found the MOV's hard to get so I skipped them and the safety gap you'll have to build.

I hope this gives you some help,

I don't, but in order to do so without wrecking the transformer it is
imperative to keep the wires wetween the transformer secondary and TC
sparkgap as short as possible (like a few inches). The main gap _is_
the safety gap by proxy so it is also imperative to keep the gap
setting at or below the o/c peak output voltage of the transformer.
    If both the above conditions are not adhered to it would be wise
to include a filter.
