Default AVO CT160 top cap connector panel -- plugs needed

I need to make two new top cap connector cables but do not have the plugs that fit into the panel holes. Information about suitable type / where to buy or even purchase offers will be appreciated.

Thanks in advance, Karsten

There is a thread about that on this forum here https://www.vintage-radio.net/forum/...ad.php?t=32609

Looks like it is 3/32" (2.38mm).

It looks like power entry jacks (such as for a wall wart) are 2.35mm diameter. For example https://uk.farnell.com/lumberg/1636-...ngdom%2Fsearch .

Perhaps that would work?

Here's another possibility - a split pin like https://uk.rs-online.com/web/p/split-pins/0270136/ which is 3/32" diameter. Solder on a wire and heat shrink insulation.

This was a thread that I started 11 years ago, I ended up with a vintage plug that I found but can't remember where, I had to modify it by cutting off the original pin and soldering in a new solid brass one which is 2.3mm diameter, it fits very well and as Craig says it will be 3/32" diameter, the pin is slightly too long at 19mm and could be shortened to 16mm, I've got a lathe so the modification was quite easy.

Thanks to everybody who has replied to my inquiry. 3/32" diameter appears to be the really important information. I will try the (slightly too thin?) Lumberg plug and maybe also ask a friend who has a lathe to make two from standard slotted 4 mm banana plugs.

I had reasonable success when I was stuck for these by using 2.5mm audio plugs.

I'm going to try the 3/32 split pin - having come up with it I ought to put my money where my mouth is. I've bought a small quantity of brass ones from a guy on eBay, which should be easily solderable. The pin ought to spread a little to make a good push connection.

I can confirm that a 3/32 split pin works perfectly! I bought some brass ones that I can easily solder to. The pin can be opened out a bit to make a nice sprung connection.
