Ypu have forgotten the project I worked on - the pocket television.

After taking ten years of advance orders, he shipped just enough rubbish

I left because i told him it wouldn't work,

Did it work?

That is understandable.

and I told her what to do.

Did she do it? Did she do what they do at the snotty unis's?

Complete tosser,

No taste in clothes or haircuts.

She was a such a loser, and no taste in clothes either, and always backed
the losers too. She even backed Archer too, who claimed to have been to
snotty uni, but nver and no doubt did what they did. Maggie probably did
what all the others do at the snotty uni's and that was why she was like
that.

I'd burn 'em all.

There were two PWM amplifier products, IIRC, the X-10 and the X-20.
These were 10 and 20 'watt' (that's Sinclair watts, not SI watts)
supposedly hi-fi amps. They came as kits - just a bare PCB and handful
of components - no housing of any kind.

I had an X-10 and also failed to make it work in any meaningful fashion.
There was no filtering of any kind on the output, so the RFI generated
was considerable: enough to wipe out LW and MW radio reception for a
considerable radius. I did get some audio o/p - into a Goodmans Axiette
8 (more nostalgia) - but hi-fi it certainly wasn't, more like 50% THD. I
gave up on it and never bought another Sinclair product, ever. In
contrast the Mullard 3-3 valve amp design I'd built a year or so before
worked very nicely for several years, eventually being replaced by the
Bailey 30W transistor design published in the Wireless World (~ 1968).

yep. same here. Excellent that Bailey was,. I mena, it worked!

I've still got the X-10 in its original box somewhere in the loft. I
wonder if it's a valuable collector's item by now?


only if you are into industrial pornograhy :-)

He did as much for wife swapping as Tony has done for iresponsible
lying. That place was a complete shagshack.

forced to agree with you, as long as we can use Bliar and prescott as
firelighters, and that revolting little squinter.

Which one? One of the class A designs or the AB 75 watt jobbie?

Ah. A real oddity. Chartwell kits sold to BBC staff.

Got another pair in the kitchen - made by Rogers.

Ah, a subtle hint that it doesn't matter who made Dave's
speakers as all LS3/5a's sound the same. :-)

I doubt any two speakers sound exactly the same if you were to measure
accurately enough. However, my Chartwell pair have adjustable crossovers
so I set them to match the Rogers as closely as possible. One of each used
as a pair but switched to mono gives a pretty stable central image.
