Extra low? Never had a standard banana type arc or cause a problem this way, and used them up to at least several hundred volts. The Simpsons used them from the 3 series until the 7 series, IIRC.

I have a pair on the end of a cable feeding HT of around 2kV to a 144MHz tube based linear, and they have never given me any problems. Arfa

I managed to pick up a 60's era Unigor 3 made by Goerz (Austria) on Ebay and this has a 5kV input range on it.

Regular bananas have been safely used for decades plus. I don't doubt that somewhere along the line somebody probably sued somebody and this is why we now have those ridiculous inverted bananas, but I won't accept them for normal applications. Mark Z.
