|Drip Electronics OPTO 6 version of the 1968 LA2A|
The full details of the device are online at Drip Electronics: OPTO 6 (LA2A). They build a PCB to approximate the old point to point wiring typically found under tube systems as well as build the custom electro-optical cells.
Now I am not a tube guy nor an audio guy but any electronics that glows when it is working is good electronics.
