How short is the cable between the transformer and the grid? It's best with fraction of inches. I'd start with a value about ten times the output impedance of the transformer and then come down with a substitution box. Try 25pf, then 50 pf in series and if that doesn't work go to 100pf and so on. Don't use any more capacitance than you have to. James
