[Milsurplus] TS-16 test set for APN-1 Altimeter - info wanted

[Dave]

Hello all,
i have an APN-1 for demonstration purposes at club meetings 
and events. I use one of it's test sets, the TS-16, to 
demonstrate how it works. However, my TS-16 has failed me 
and I have no information to help check it out.
Does anyone have a copy of at least the schematic, but 
better still, a manual, please?. I have the manuals for the 
APN-1 but not for any of it's test gear.
Cheers
Dave
