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.
