Replace screen taps w/pot Zenith

[TinCanAlley]

Anyone know where I can get the connectors like the ones on the tap wires (the white crimped piece)? I'm going to replace the taps with 5K pots and decided the best way to do that, with little modification of original, is to make a piggy back card that will have the pots on the tops side and the plugs on the bottom side. I can then just sit it directly on top of the terminal strip shown in the pic of the post just before this one.

The connectors would sit directly on the HI pins and then the current wires would be connected to pins on the board. I could then more precisely tune them and if necessary, remove it and be back to factory.

Oh, and one more question. I noticed in the schematics that the resistors used in that section are all 1/2 watt. Does that mean I can use a 1/2 watt pot, or should I go higher? There seems to be up to 180V passing through it.
