This is minute...

That is fab ...

http://livinginthepast-audioweb.co.uk/imagex/misc/icon_lurker.gif Lurking. I did a Bantam sort of like this once (well twice actually), wasn't as tidy as this tho. (Especially the first time) I only found out recently that honing a cylinder is about making a slightly roughened surface that can hold...

I thought you'd decided you were earlier?

"What the hell Lois, why don't I have a real check-book?"

"Peter, where do checks come from?"

"Er, when a mummy and daddy love each other ...?"

"That's why."

I like the resin filled toroids with holes, did they come like that?

This was the type I last used. https://www.hificollective.co.uk/potentiometers/coupler.html Next time I'd use a piece of rubber (or similar) tube. Ta, yep looks just like what RS stocked. Re rubber tubes etc., didn't have luck with those sorts of ideas in the past. Depends how stiff the shaft is to...

You know what I did think could use a spindle coupler (simpler!) however the control direction would then be "backwards"


And on the subject of spindle couplers, these seem to be like rocking horse droppings lately? I can remember getting packs of 5 from RS? But can't find them now?

Re sceen current, yes I get screen current but it does not equate to that of a real valve. this is something I've found especially frustrating. E.g. I set up a text book circuit for a EF86, the anode...

How you getting on with version XVII ? There were lots of complaints about it on the Yahoo LTspice user group. Things just not working properly or not as before. Might have been sorted by now, but is why I'm still sticking to version IV. Coupla notes re using the valve models. It is quite easy to 'b...

DUH!! I've just seen in item title "ALPS", so there you go then.

but I’m not convinced about the quality of the pot. Any other suggestions, anyone?

That thar looks very like a servo-driven Alps pot, so OK if you like Alps pots.

I remember seeing about the servo drive option in Alps datasheet.

Yes there are radio oscillators that use crystals for tight channel stability.
