Litz wire - that brings back memories.

I remember an article in a hi-fi mag sometime in the early 70's where
some pillock (actually a Frenchman) noted that he had rewired the
connections to his front door bell in Litz wire and it improved the
'tintinabular sonority' of the bell when it rang.

Then we got oxygen free copper, unidirectional signal wires (oh yes we
did) and on and on.........

Oh joy of memories.

That was my first record player. My brother got me it second hand in

the wire looks like 36SWG coil wire but the enamel is designed to evaporate
when touched with an iron. There was a warning with the kit I
bought that this gave off a small amount cyanide, and it should
be soldered in a well ventilated area.


I remember it well

Do like the Arabs. Wipe with the left, eat with the right.

Bu**er if your left handed;!..

No, apparently they can do it the other way round if they like. But when
lefthanders pass someone else a piece of cake they usually say, "Don't worry
love, I wipe with the other hand."

Well, unidirectional signal cables are well documented. See

Blimey! That's probably why I'm dead!

I had an Alba (like a Dansette but cheaper). I fitted a stereo cartridge and
fed the two outputs to (a) a Sinclair transistor amp, and (b) the gram
socket of a pre-war radio. The speakers were Wharfdale 8" co-axial built
into concrete pipes. It all worked splendidly, or so it seemed at the time.
I had to run the Sinclair off an old car battery because I hadn't got a 12V
psu.

I got a mention on the Light Programme because of the apeakers. I walked
tall the next day, I can tell you.

I won't argue with that Bill, but we are talking 1970's and audio here -
semiconductors were still (compared with today) in their teens (possibly
a bit more than infancy) and use of that technology for cables just
didn't exist.

It was all snake oil - as it still is with the likes of Russ Andrews -
but many people were happy to pay ridiculous prices for 'fancy' cables.

If you want a laugh get on Russ Andrews' mailing list and look at the
stuff he sends out occassionally. I got one a few weeks ago and I
couldn't believe what he was saying. I couldn't cry, I was laughing so
much! The worrying thing is that there are clearly suckers out there who
believe it. An example: a mains plug for the removal of spikes from the
supply - i.e. it contains a couple of varistors costing at tops about
40p each - sell for anything between £18 and £255 - yes that is right,
two hundred and fifty five pounds!

We used to nick blasting wire from the quarry. It was single strand and
plastic insulated, and very useful. You could find miles of it in the
quarry. It was strong enough to make long wire aerials with.

Why do I have such fond memories of rigging long wire aerials, in my
teens? The first effort was for my crystal set. Later I found a
telegraph pole with the open wire insulators still on, lying by the
side of a country road, and used a couple for the second aerial, for
my 19 set, from my bedroom window to the bottom of the garden. I fixed
my old scout stave to one of mum's clothes poles, to support the far
end. I'm not particularly proud of that particular bit, but I
certainly enjoyed the business. Maybe I should have gone into aerial
rigging instead of boring old computing. But maybe that would have
gotten just as boring if I'd done it long enough. Bill?

What a waste of money. You do know that the higher the aerial, the further
the electrons have to fall, so they are moving faster when they get to your
TV and so the signal is stronger, and no need for fancy cable.
