Replies to request for input cable for an old CRO.
Not sure if it has been answered but Jaycar has the BNC cables and connectors.
I use the following all the time to connect input signals to our CROs:

Jaycar, Altronics, RS Components, should all have some oscilloscope probes or adapters.
Examples from Jaycar – https://www.jaycar.com.au/cro-oscilloscope-probe-cable-set/p/QC1902
BNC to double binding post (should be 4mm) is cheaper – https://www.jaycar.com.au/bnc-male-to-double-binding-posts-banana-sockets/p/PA3666
Or coaxial cable, male BNC to 4mm male test connectors (usually stackable at this end) – https://www.rs-online.vn/p/bnc-plg-to-4mm-plg-rg58-cable50ohm-1-2m/0488595/
I use this type for most demo setups as a 4mm socket is pretty standard on a lot of instruments these days, e.g. the output of PASCO function generators.
I often plug one of these leads into a function generator and onto the scope and stack some leads to a speaker into the 4mm plugs. The 4mm plug accepts crocodile clips, including large, insulated ones, or you can buy cables with the clips already fitted, but these are not as versatile. https://www.rs-online.vn/p/cable-bnc-croc-clips-1-2m/5260241/ If you do not need to probe around a circuit, I would recommend trying the coax with BNC and 4mm test plugs. Please be aware that I just noticed my RS links are to their Vietnam website.
We bought a replacement one through Perth Scientific a little while ago, so they should still be able to help.
There is a museum in Wireless Hill Park in Applecross with plenty of old equipment and they may be able to help you with spare parts.
Richard Rennie used to be in charge and may still be there but I suspect there will be other volunteers.
