Can anyone put name/type to this two-pin speaker connector as used on a Specto 5-10 amplifier.

One spade connector is 0.2 inch, and the other is 0.15 inch wide.

I’m after a pair of these, however, before looking for a pair it would help if I had a name/type etc.

Hello,

Many thanks for the prompt reply, it’s really appreciated.

Wow! didn’t expect it to be in the Digikey catalogue. We have a Digikey account at the works.

It just goes to show the longevity of some connectors as the Specto amplifier dates to 1955, and here we are, nearly 70 years on, it’s still available.

Regards
Terry.

Yes, the Cinch-Jones connectors were workhorses in all sorts of things from the 1950s onwards: Military, instrumentation, audio [Jukeboxes often used them, as did quite a bit of British HiFi stuff from the likes of Quad on the II/22 for providing power connections to preamps and tuners], movie-projection equipment, ham-radio stuff [a lot of late-1960s/early-70s Japanese gear used them for mains connectors!] early Moog synthesizers, and TV/FM antenna-rotators used them too.

Tough, consistently reliable, easy to install. That only really faded out when the crimp-on plastic shelled Molex/Amphenol connectors appeared on the scene.

Last time I looked the same people were still making the 6-pin Jones connector as used on the Quad II as well. The shell is plastic now, but otherwise it's the same as back in 1953 (and earlier, no doubt). I'm not sure it would be rated for 360VDC (which is what it carries between pins 3 and 4) these days though !

Cheers,

GJ

That brings back lots of memories, we used the four pin version as “ snatch” connectors.
