Graphtec Thermal Arraycorder WR7700 1991 test teardown

Super fantastic 8ch recorder, I even think it got a 16 ch mode, if I use the 4 inputs on the side each with 4 ch input in them, it really works so well, is very silent and smooth, only tiny detail was the battery for time and date, was defective, so i replaced the 3 cell ni-cd pack with one cell lithium,
this one was purchased in 1991 for 48000 DKK = 7000 $
