What kind of pots on early 80s Dynacord delay?

[CJ Miller]

I bought a Dynacord DDL12 delay rack "as-is" for $12 in the winter. The outside is a little scratched up, but the inside looks excellent. It blew a fuse for some reason, I'll need to investigate.

On the front panel, one pot had its shaft broken off. I have never seen these kinds of pots before! They are square-ish in back. Almost completely open on bottom. The shafts appear to be removable, held on with "C" clips. And the shaft size is one I have never seen elsewhere, they are maybe 4mm across?

Can anybody tell me what size and make these might be? I'd like to replace this one with the original kind, or else I'll probably replace them all - which is more work. TIA!

I suspect a photo would help us in helping you hunt down this elusive part.

As a source of odd components, that might fit what you are looking for, why not have a look at Surplus Sales in Nebraska, here:

they have a good collection of odd parts that you may find fits the bill.

Good hunting.

Ask Dynacord.

They´re really helpfull with their old stuff, seriuosly. Best customer support I ever had to deal with. They still have Eproms for their old stuff, and you can get every schematic.

Try it.

Best wishes,
