Sound system for old village hall

Yeah that's a common connector for 'fixed-install' sound equipment, the scalloping on one side is the distinguishing feature, don't know what they're called though, as the stuff I work with (live music for churches) is the transportable type with robust 'Speakon', 'XLR' and 'jack' connectors. I have seen them on outputs from induction-loop amplifiers (for hearing aids), but they can be used for all other types of audio and control circuits.

This book is very good, all you need to know about speech PA systems:

The connector is made by 'Phoenix', and is a common type of connector on the speaker outputs of amplifier intended to drive 100V speaker lines.

RS and Farnell sell, them, but measure the pin-to-pin distance accurately, as there are many size variants that are difficult to distinguish between on the catalogue page or web site screen!

Blimey. Is that your bedtime reading...

..I know I had memorised the general specs on about 1000 transistors at one time..

I thought so too except molex are generally white polyythene..it might be Amphenol.

I think that fits with the statement in the manual that its a screw connector - looks like that female bit should have been there with the amp,. and its missing.
