Hi All Ive just aquired two neon sign xfrmers240v 15kv 30ma im in aus and I imagine they would have similar units in the US they are italian made F.A.R.T. units they are a resin block design I was wondering if anyone has used these for coil work because if they burn i dont see no way of repairing them. BTW wants to know where Mark Finnis gets them beautiful toroids made. Pete the TV repairman
