Hi,
After our house move, I noticed that something was rattling in the LAB-1. I disassembled the unit, and found that there was some piece of plastic wedged (not from the LAB-1, probably something that was in the box in which it was shipped) between the PCB and the front panel of the power supply. I disconnected all cables, and took the foreign object out.
As I wanted to clean the dust out of the LAB-1, I left it for a couple of days. Now, I want to reassemble it.
However… I forgot to note down which cable goes to which connector. CH2 is easy, there is only one cable that has 4 pins…
The problem is with CH4 and CH3… They are both 3 pins. Which one does the 317T connect to? I think it is CH4, from a schematic I found on the net, but I would like to be sure.
Thanks in advance!
