Yes, that is the connector for the HV lead that goes to the CRT Post Deflection Accelerator (PDA) electrode. The PDA is a conducting coating on the inside of the tube funnel that starts after the horizontal deflection plates.. You should be aware that the outer coating of the tube forms a capacitor that holds a high voltage charge for a long time. If you disconnect the HV connector, be careful that the lead does not come in contact with any circuitry as it will damage it.

Is this the PDA?

I was thinking it was the end of the HV mulitplier...
