this seems to be an increasingly common occurrence with multimeters and other test equipment, where mechanical components are failing within a few years of purchase. yet i use older gear dating from the 1990's that have been subject to significant wear-and-tear without bits 'breaking off'. i just had a look at an HP34401A and see it has solid copper tubes where the shrouded banana plugs fit in; a Fluke 8842A has machined brass with a chrome plating.
i'm not wanting to criticize Dave, but...
1. it is not fair to expect better from modern manufacturers? how functional will (for example) a 121GW be 10 years from now? or a Fluke 87V, that i believe suffers similar failures.
2. why hasn't someone come up with a retrofit for such pieces of relatively expensive gear? sockets made out of solid copper that can be fitted in place of the current ones that seem to keep failing. it seems that something could be turned out by an automatic lathe for minimal per-piece cost.
Dave: my apologies, i think you are doing a sterling job helping out owners of the affected gear. my criticisms are for the manufacturers who must surely be aware of the failings.
cheers,
rob :-)

I wonder are the replacement terminal still available ? I am not using the meter on the road etc, its exclusively used on the bench in my hobby lab. I don't post the SN of the 121GW here but I can ofc on request give it. I also have the invoice of Welectron where I bought the meter on the 28/08/2019.

Because you bought it from Welectron, they will have to handle support, so I can't send a free replacement, but if you want to pay for shipping I can send one. I'm not sure if they offer the jack.

But what is the arrangement for the serial numbers that had the known issue (if snoozer's DMM S/N is within that range)? Is Welectron handling those as well? Since it was purchased in 2019...

I have no insight into what Welectron do, they buy the meter direct from Kane Test and handle their own support.
LeifG:
I have a multimeter 121GW where a banana probe connection has broken.
Searched and saw a post about broken probe connections.
My question is if it is still possible to get a replacement part?
If it can be obtained, I need to know how to proceed.
