Way back in the dim & distant past, when I was still working, I rebuilt an ammeter for a friend and blogged it as ‘Tim’s Ammeter’. This is another one, a similar 0-8-0 amp CZU27 from the Huntmaster kit. It’s not in bad shape.
It’s a bit grubby and scratched as you might expect, so I will pull it apart for a clean. There isn’t much glue on this one and it comes apart easily.
All in bits with nothing broken:
Here’s a curiosity - it’s dated January 1960. It must have been replaced at some time, though it’s correct for 1958.
It cleans up nicely.
This is interesting. The power supply is set up for constant current:
These aren’t hugely accurate! This is actually at full scale deflection, but as you can see it’s only passing 7 amps.
