Separate power supply - Umblical Cord
Hi,
I am building a separate power supply for my 2a3 SET amplifier.
What is the best connectors and wire (gauge, stranded/solid?) to build the umbilical power cords?
I am thinking of:
a) XLR 4 pin for the bias voltages (300v, 280v). 23 Gauge solid silver cable
c) XLR 7 pin for the heater supply (2 pin each for the 2x 2a3 Heaters and 2 pins for the driver heater). 18 Gauge stranded copper.
Should I add a copper shield then a PVC insulation over the power cord?
Thanks,
Marcus
