I am restoring a Star Wars Cockpit and I have pieced together a 25" Amplifone setup. I picked up a rebuilt tube from Scotty at Hawk Eye Picture tube. Anyway I had it working briefly but when I adjusted the X-Size pot at R25/R24 the picture went out. I am getting deflection chatter, the led is not lit on the delfection pcb. The over voltage led is not lit on the HV Pcb. All fuses check ok on deflection pcb. There is no neck/heater glow. Could I have blown something by overdriving the X-Size pot ?

Please help !
