Re: 475A horizontal amplifier problem

I don’t know how you got access to the X deflection pins on the CRT through the hole in the interface board. Keyhole surgery? It might have been easier to remove the CRT after unsoldering the X amp output wires (red and green go through the hole). Attach a puller wire to them so that you can pull them back through the hole after checking the X deflection connections. Even so that is fiddly as you have to remove the 4 Y deflection wires, and they are not easy to put back.
