My NOS flyback seems to be a dud. Had to repair two leads eaten away by corrosion. Hooked it up and heard the typical high pitched whine, but no HV. Tests good on my EICO 944, but am concerned there might be another break somewhere.

Put the old one back in and subbed a string of 1N5408 diodes for the damper. The bright line went away but it did introduce some oscillations resulting in faint vertical bands on the screen.

Have a NOS 25W4 on the way
