Will take some pictures shortly and send them along. Warning: I must have taken everything apart 10 or more times and rearranged and resoldered. Not pretty… but works fine. Still on my first 9 volt battery. You don’t use much energy changing volumes levels once and a while. I put the LED on the volume knob to remind me to shut it off when I turn off the main power and tube heaters. So far so good. Thanks for your interest.
