Heybrook HB100 speakers?
Hello all. I was in a secondhand shop the other day in Limoges in Central France (I live in Correze) and I made an impulse purchase of some old UK made speakers, by a small company from Devon called Heybrook. The model is Heybrook HB100 (serial number 001001). I think they are now defunct but managed to find some info on the HB1and HB2 speakers but very little on the HB100. I'm guessing it is a later model as it look's like an early 90's design. They are in very good order, but the only problem I have discovered is that the plastic nuts on the four rear binding posts (for bi-wiring) are very worn in the plastic thread so they will not tighten up properly.I tried a pair of nuts off some Mission speakers but they appear to be about 4mm posts and on the Heybrooks they are more like 9mm?
Can anyone advise? Are there standard sizes of binding posts/nuts. The ones on the Heybrooks are pretty hefty. I would rather just replace the nuts with some metal threaded ones but don't know what size to order or where best to source? It's more work to replace the actual posts. I have tried banana plugs into the centre of the binding posts but they don't go all the way in?
For the speakers I think they are 100 watts and 6 ohm, but that's all I can find...is Heybrook stuff any good?
A link to some photos of the speakers and connections on the rear.

The ones on the HB may have come from Cliff Components.

Someone may know the answer to your questions, of course.

I suspect you'll be best off replacing all the binding posts with a modern equivalent to be honest. Or, a simple metal nut to clamp spades down? I doubt you'll find knurled ones.
Don't worry too much about the plugs not going in all the way, they often do not (it's just masked by the lip of the plastic nut). Newer binding posts would likely cure that.
