Tray rebuild, (but with a fault)!

Back in January this year I rebuilt my twin 70 watt tray, complete with separate gear switches, but long story short, the Philips ballast I suspect had a fault? Seen here running twin Slovakian, Osram SON-E, (both new), but the Philips ballast was running one lamp at 104 volts, and both the capacitor and ignitor were getting warm! I’ve now swapped the Philips with a Parmar.
