Adding tracking to a TS3022S PSU as per model TSTS3023S

[hazzer]

I have the TS3022S and on a recent project found I was having to manual track the outputs, later I decided to see what would be involved in adding a tacking option to the twin output PSU. Searching the web I found there was ano version, the TS3023S, with triple outputs and tracking.

It looks to be quite a straight forward mod - just 1 DPDT switch and some resistors - though the switch does have to be rated to the full output current - the manual describes the front panel switches as having gold on silver contacts.

For anyone wanting to look into this mod - I've posted below links to the circuit and the user manual describing the tracking feature on a TS3023S.

My switches are on order......  more when its up and running.
