If it says it requires no rewiring, use the tester settings for the original CRT 17DAP4 type but use a 6.3 volt filament voltage rather than 2.68.

2.3 volts was for the 21" CRTs.


If you are worried about using too high a filament voltage, start at 2.68 volts and if it barley glows, turn it up to 6.3.

No, the flyback isn't ruing. You just need to reattach the plate cap lead. Remove the remains of the old lead from the cap. Very carefully strip and tin the end of the wire and solder onto the cap.

The big concern is to not break the wire off from the flyback.
