Re: Thermionic Valves

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 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...
