SSTC Interrupter Pots connect by long wires to pcb (half meter or so)

Hey
I have made a simple NE555 interrupter with two potentiometers to adjust on/off times (like Steve's Ward).
I have connected the potentiometers on around 50cm wires to the PCB, so I can adjust it while standing far from SSTC.
But now the Tesla works very bad and there are almost no sparks when powering it from 100V, while before there was around 3-4 cm.
I haven't tested it yet, but it seems that the long wires are causing interference?
Can I somehow improve it? Or is this a bad idea in general?

Keep wires as short as you can, perhaps twist together if possible. Wrap a few times around a ferrite toroid. Also enclosing in a metal project box may help.
