I have started building another plasma speaker based off a design from HV Labs

I was wondering if anyone else has built this design and if they made any changes to make it better? Also can I use a IRF644 mosfet instead of the FQA55N10? or any of these

EDIT: this should have gone in the high voltage thread, sorry, it was late when I posted

EDIT EDIT: also, what do the arrows signify? IE the 20k pot, does the arrow mean tie pin 2 to pin 3?
also, does anyone know of anything i can do to protect the audio source from reverse voltage spikes?
