Just feel like showing off some new acquisitions.
One is missing the battery unit (this was one of those eBay bids you don't really expect to win, and it tipped over Australia's 1k point where a heap of duties are due), so I ended up buying the second (I think this is also one of the ex-ADF units that all came on the market at once).
I plan to have a mate clone the metalwork for the battery unit, and the board's pretty trivial.
The 196 here probably hasn't seen a cal in over a decade, so this was more getting lucky when I turned one of the standards on that it started a touch low and came up as it heated up. The other one is far enough out it might end up as a parts unit.
