porthole flyback shorted - any replacements ?

[kramden66]

If you've been following the 24G26 thread i was there , it was up and running , well to try help with the somewhat unstable horz hold i decided to try changing some of the sync and horz tubes , to my shock i lost raster , went up and down everything and couldn't find anything wrong , no hv on the anode , so i hooked up the fly tester and it shows a shorted fly.... so my question is is there something i can sub it with , the fly i listed in the wanted will do it , also the fly listed covers multiple zenith portholes including the 10" mayflower , i think it was Eric H who adapted a fly-1 to that set , could a fly-1 work here ? or is there something that could sub ?

sorry did it again posthole instead of porthole.

thanks
