[Amps] HT-41 Refurb

[Merle Bone]

I have a friend that has an HT-41 amplifier that we wants to refurbish and use. Because of the weight of the amplifier, he would like to put the high voltage transformer on a separate chassis and put it on the floor behind his operating desk. He wants to simply remote the wires for the single winding 110V. primary and the "center tapped" secondary up about 3 or 4 feet and into the HT-41 main chassis. 

I would appreciate your comments on any special issues to be considered ( packaging/strength, voltage insulation, RF leakage), possible approaches (connectors,cable,conduit) and any other comments you might have to help him achieve this approach.
Thanks & 73, Merle - W0EWM
