Repair of Hever Level Generator

[johnh]

Found Heuer LG11 Level Generator 200 Hz to 4000 Hz  in the skip at work a while ago http://www.heuer.com.au/tmsa11/lg11.html

It was little beaten up, scratched missing the battery holder and door. Some had attacked the torx screws with a hacksaw so they could use a flat bladed screwdriver.

It comprises three board. The front panel has display and other controls  processor card  and the output card

After pulling it apart you could see that the batteries must have leaked at some stage. Replaced the battery connector and replaced 4 AA battery holder

Made a new battery compartment door from a blank PCB
