The acrylic is from a bad piece at work, I just had to cut it in half. For the tube socket holes a regular hole saw is quick through plastic, even melts it a little bit. I put in plastic inserts for all of the tube sockets and brackets. The only screws showing are for the transformers and the aluminum on the back and rear of the sides. The local heating and AC place cut the aluminum and I bent it using a HF bending brake and a PVC pipe. Probably needed a steel pipe, because the PVC bent too much. There's more acrylic underneath with slits cut in for ventilation. Underneath I made eyelet boards, they work fine and all, but the eye is kinda small. It's my first all German tubed stereo.
I also learned how to set the bias on a directly connected cathodyne phase splitter. The EL12s run with about -18 volts on the control grid.
It was $6 for the aluminum, $0 for the plastic, $3 screws and nuts.
At first I wanted to be a ET. Now I are one.
