As an update, I managed to find a NOS ECG561 tripler for a fair price. I still don't even know 100% that is crosses, but the appropriate amount of terminals are there. Do these hold up any better/worse than Zenith parts?
I just applied silicone to the input pin and will wait until tomorrow night to try powering it up.
As a side note, I managed to snap in half the clip that covers the focus and control pins when trying to reinstall it. I figure nothing is done without a reason, should I silicone these wires given that the cover broke?
