No probs, should you want to build a "tube" amp I'm sure I can help. I'm no expert though, but seemed to have managed to have built 20 or so amps to date.
SETs are my flavour, as opposed to PP.

Valves... Tubes... I work with 2 Brits who are determined to teach me 'proper' English! :smart:

You only think you work with them, they are the initial infiltration, preparing you for when we make our comeback, and turn you into a colony again. :D

Shhh, we've almost got them under control John.....see, we got them to set up this site for us and it was done willingly to boot.
Like I said, almost there :lol:

If you can fix the economy, you are more than welcome to it. :lol: :poke:

Right you lot, back to the topic :D
I need to make some sort of connector for the top to pins of the valve. One pin is at a very low voltage (the Grid) and the other is at a very lethal high voltage.
Lethal as in you'd only get the one chance to touch it cos you won't be around for a second go...!!
So obviously whatever is made for this pin needs good insulation. I was thinking of using some of that Teflon that made an appearance earlier.
At the mo, the following may or may not be the final choice. I'll press on with it and see how it goes.
Suggestions are more than welcome.
Taking a 15mm copper water pipe and sizing it up to the pin in question.
Cleaned it up on the lathe and tapered the end internally.
Onto the miller held in a hexagon collet fixture in order to make three slits at 120deg.
Starting to make the first cut and it's cutting really smoothly.
All three cuts now done
Then turned a bar on the lathe to the same dia of the valve pin to open out the end of the slitted tube. This was to prevent too much force on the valve itself.
Well that's where I'm at and I'm not quite sure where I'm going with this. It's the fact that it needs insulating that adds complications, otherwise it would be a simple matter to make some sort of clamp.
Design in progress...... :)
