In this video i give an update on the Polygraphs that i bought, so far the 7D Polygraph has been dismantled as too has the 2nd oscillograph / chart recorder.
I take a quick look at the 78D Polygraph, in the near future i will be taking a close look inside every section of this unit in more detail. Thankfully the parts from the other two machines have served to bring this one back into a more functional state but i have yet to turn it on.

The power switch is repaired and the calculator proves to be working.
