1K Pot
- April 2011: rearrange cables and wiring for the installation of SQUID-wires and HF-coax cables.
- Strange Heat Sink for Heat Switch (removed!!!)
This is one of two former Heat Switches. They were connected with leads to the mixing chamber. The resistance of the heat switch was 1k. The led-HS was connected to Pin Bar B, the other one to Pin Bar F(8|16).
