There are some cross references to other manufacturer's equivalents
at:

They'll be Beckman 62P series - the 8333S and 8321S are probably
date of manufacture - week 33 and week 21 of 1983.

Different pin orientation perhaps?

Thanks,  I eventually worked it it out and found that same crossreference pdf.  

2 things tricked me however,  the first is a stupid mixup between R100K and 100R,  I wont make that mistake again.

The second is that you can have two diferent pin positions on that series of pots,  one has the pins near the middle, and the other round the outside,  its the middle position you need for the SDS5.

so with that sorted,  now im looking for the bigger pots, the ones that come through the front panel.

Im also planning to bring the filter Q control R27 and filter dynamic sweep R25 out to pots somehow.
