At last my compressor unit is finished! The knobs are in place, and the resistor in series with the VU meter lamp is mounted. The only thing left is whether I want to engrave the front plate, but I’ll try to use it for a period and figure out whether it’s worth it. After all, I have to dismount all the pots, switches and the VU meter, let alone the engraving-process itself (which I have never done before). We’ll see.
