4 knob Concentric with DIP switches

[David Goodridge]

Good afternoon and happy new year, got a question for you all..Hopefully Ken will chime in.
I have the 4 knob Concentric Smith Electronics with the DIP switches installed and set to the original settings. It is the 9 V circuit, so am I right in assuming that the new settings would have no effect on a 9 V unit? As I believe the new settings are set up for the 18 V unit.

For the mid range controls on the DIP, does the lowest (normal ) setting on the diagram, mean that it has the lowest mid range output?

Just thought I would ask.
