Large fluted knobs w/pointers

Postby JosephMax » Mon Jul 23, 2012 3:20 am

This is a great find! If you're looking for the knobs you need for the Rate dials of a Hieronymus Machine, (Or a BIG tuning knob for any device) this is the place.

(Scroll down to the bottom)

This is a knock-off of the Ohmite 5111A knobs that typically sell for US$20 to $25 each.

$5.00 each or four for $16.00!

This is a really hard to find component and is necessary for the Hieronymus Machine. The Rate dials MUST have a conductive shaft collar and a conductive metal pointer. Often people end up fabricating their own because they're so hard to find (and expensive when you do find them!)

That's a great find Joseph!! I fancy making my own Hieronymus analyzer so these will come in handy. While on the subject of vintage dials, do you know anywhere that sells the type used by the De La Warr broadcasters, as one of mine is shot, and I need to replace it?

It's hard to tell the shape from that picture, can you take a side-view? And what is the diameter at the base and at the top?

It might be difficult to find an exact match. You may end up having to replace the whole set with something that's close, but still vintage.

Thanks, The bottom of the dial is 31mm diameter, and the top is 20mm it accepts a 6mm spindle. Any idea on a source for these?

Those are very unique. I don't think I've seen any like them before, and I've researched a lot of knobs!

But I'll look around and see what I can find, I have a lot of antique radio knob sources bookmarked. I'll look for possible alternatives of the same vintage also.

I get some small ones on ebay uk for my instruments, and they look pretty good as well. I think these may be a bit larger, or there's the other seller:
