Good grief. Considering the number of such terminals in the average
house carrying a great deal more current, I'm surprised there's not
fires everywhere. ;-)

The number of mains plugs I've removed that are very very loose is
amazing.

Not only mains plugs I've just selected two ring mains sockets at random and
one terminal was loose and the others could take a tightening.
the loose wire had not arced because the two conductors were twisted
together. Some sunny day I'll go around the lot.
How's your mains?.......is that a burger frying? Don't lose any sleep over
it ;-)

Well, yes. Not properly tightened in the first place.

Its just informing HiFi folk (who are generally fussy) that they can tighten
down connections some more - no harm in that. Considering houses are not
subject to constant vibration this hardly applies to domestic ring mains,
cookers etc. Actually there are quite a few incidents of arcing and
localised heating due to loose 13A socket terminal connections but because
the area being metal clad and grounded it generally goes no further (ask any
leccy)

Yes - I've come across it several times. Due to inadequate tightening in
the first place. I'm inclined to think even deliberate by some
electricians to make more (chargeable) work for them later. However, I've
not known of any of the things I've installed - quite a few over the years
- give trouble in this respect. I do them up until they groan. ;-)

That's why house wiring is required to be solid core, and plugs have
fuses in them................

BTW, that's still good advice even if you are wiring a house - go
round the junction boxes again the next day. You'd be surprised how
often you'll get an extra half-turn.

Hi,

Looking to replace my bi-wired speaker cable terminations. My local hi-fi
dealer is selling banana plugs at £1.50 which are the ones which don't need
soldering.

Does anyone know where I purchase these online cheaper?

Are they as easy to fit as the dealer says?

Also, what are the best type of terminations ... spade or banana?

Neutrik Speakons actually ! The only connector ever actually specifically
designed as a *speaker* connector. Will accomadate up to 4mm^2 csa wire.

Like the pros use.

I've just completed testing of a prototype amplifier with Speakons and 4mm
bananas in parallel. Those who have listened to it "prefer" the
bananas!!!!!! I have no explanation.

The only possible explanation is that the banana plugs introduce
resistance and your listeners prefer flabby bass. Do they also prefer
valve power amps?
