I picked up an old R.S. Archer Time Base Generator (kit?) and when I opened the metal case up the PCB was stuffed with components, but the circuitry was not wired to the front panel rotary switch, the power LED wasn't connected and ditto with the internal/external source switch. Not a high buck item, but I'd like to play around with it and finish it. There's a bunch of marked holes on the pcb for wires going to these things, but they are not labeled other than "A" - "M" (I think) and so no clue as to which ones go where. Can someone supply me with a copy, or a link to, the assembly instructions/schematics so I can finish it up. Thanks!
