I do primarely two things to those Accuphases. First is to remove the powercord and put in a simple ac-inlet, no fuses-no switch (see link)

The Next will be to hardwire the trafo directly(!) to the ac-inlet, if the trafos primarys are too short then extend them with simular size solid core copper wire. To finish this mod, get some heavy fire-alarm cable or anything else made from solid core copper conductors, absolute minimum here is 12awg. This powercable must be plugged directly into the walloutlet, no extensionwires.
Second part of the mod: the signal inlet wires on these amps goes a long way, including a volume-pot meter for each channel. Mediocre cable quality here and a volumepot too much. Find a place on the big rear panel to make holes for two new inputs, rca or xlr depending on your need. Order a few meters of the tv-coax Vivanco KX-710 and use the inner core from this coax to lead the inputsignals +/- from the New inputs to the printboard. (no need to strip the coax)
This is what these amps needs to get out their full potential. Just do not connect them with some tiny stranded speakerwires, minimum 9awg solid core
