[Boatanchors] Source for High Voltage wire

[John King]

I am reworking a 50+ year old Hallicrafters linear amplifier and need to replace the wire carrying the High Voltage from the rectifiers , High voltage filter cap and bleeder resistors.

The wire will be handling about 2,900 DC. Working voltage and a current of almost 1 AMP.

The wire must be insulated to handle the voltage but must be flexible so that it can be flexed around in the amplifier. I know that Coaxial cable is often used in projects but am not sure about the insulated center conductor being able to handle the voltage and up to 1 amp.

Three feet will be sufficient if I can find suitable wire. The old wire insulation is breaking due to years and years of heat inside the amplifier. I am afraid it will start coming of if I force it to flex into place again. Any suggestions about the type of wire that is best and available in a small quantity? Thanks and 73, John, K5PGW
