When you finish this type of radio project, how to you wire the battery hook up to an Arbe III assuming you use this or another type of battery replacement source. Do you hang out the holes wires that are referenced to the correct power voltage. I was thinking of using the color jumper cables and color code the reference to the correct voltage. I would then put a reference card inside the radio spelling out the color code. Also, do you have complete sets of vacuum tubes for each radio...the 01A tubes being real pricey? Obviously I only have one Arbe III and 5 battery operated radios. Just curious for thoughts? Thanks.

I wire each radio with cable and an octal plug for battery voltage. On the power supply end there is an octal socket. With this setup any radio can be plugged into the power supply. Once done this way you don't have to mess with individual wires.

Norm: good solution with a homemade power supply. Where do you find the multi cabled wire? Thanks.
