I might as well ask this here and see if anyone has any ideas. Not Acorn or computing related, so apologies for that. So I have a guitar amplifier -- a Laney VC30 -- which according to some commentators has a design flaw afflicting some models. Essentially, some seem to think that the speaker is mo...

A few more valves to add to my collection arrived from Bulgaria today. Although I had to go collect them from the local sorting office due to the snow.

I've been toying with re-building the super serial card for the Apple II series, but am approaching the conclusion that given they are 10-a-penny in the states (although rare here), that it might make more sense to produce something a bit more interesting that can emulate the super serial, but also...
I’ve been looking into the Mullard company (the main/biggest factory was in Blackburn - Lancashire) due to them being one of the biggest valve manufacturers in the UK (there are some brilliant videos on YouTube of the manufacturing process (lots of click clacking machines 8)) in the factory by the w...
Thanks John that’s very interestingflaxcottage wrote:That is a lovely valve. Looks to be from 1925/26. A triode output valve and probably from a battery operated radio.

On a slightly related note I have one of these for my iPod dock:- 408E84DE-9711-4992-B204-944514609345.jpeg I enjoy watching the valves warm up and glow and the one at the back changing based on the music going through it. The more recent version of mine is shown in Martin’s link by the looks of it...

Does making it a bizarre shape serve any electronic purpose? Possibly it’s due to the mechanics of the design, cost, manufacturing process, all these things go hand in hand in any design ... For example here’s a 486 DX with the size of the chip and the size of the actual bit that does all the hard ...
