Rubber covered wire on power transformers
#5

If you can carefully remove the AC Trans from chassis,(orig wiring connections marked for re-install), and get 1-side (under chassis side) of the cover off you should be able to "straighten" all the wires to insure you get new heat-shrink tubing cut-to-fit all the way back to their independant orig exits from all the orig windings coming out of their respective windings. I have saved many transformers using this method that had old deteriorated "orig crumbling rubber-wiring insulation" for many yrs. Just make sure you keep up with your "point-to-point" primary ,filaments, and HV connections. If you have a variac & ampmeter on your bench, you can carefully bring up the Trans leads repair and check all independant filament & HV rectifier plate voltages on your test bench before re-installing the trans to chassis. As you know, it is also important to make sure none of your "sleeving" fails by shorting out to AC Trans metal cover after adding or saving your leads by adding new heat-shrink tubing and/or new wiring. Me no scare of re-sleeving vintage AC transformer leads, but it is a tedious-job at best and be very careful checking the HV Plate & centertap leads!! Make sure their are no-shorts whatsoever before you re-assemble the trans metal housing assembly. Good luck with your restoration!! Randal
