Speed trim tool for SME tables?


Hi -- I have an older model SME 20/2 and the outboard psu has two trim pots for adjusting speed. I don't have the original tools that came with the table and peering down the very small trim holes I can see what appear to be brass screw heads at the end. I cannot quite make out what they are though (hex? crosshead? something else?) and am loath to go poking about in there with various tools until I know what's on the other end. Anyone know? I have an email into SME directly but thought it might be faster to check here. I'd rather not pay for a 'special' driver if this is a standard screw type.

Thank you sir. I do have manual and have everything else working fine, just felt something in an old album I'd not listened to for awhile made it sound 'fast'. Not sure I could trust my ears on this I dug out a strobe disk and sure enough, slight drift, hence my quest. Actually when I first interpreted the strobe I though it was running slow and was thinking, that can't be right, it definitely sounds fast....luckily I was just misinterpreting the strobe movement, it was fast, not slow.....yep, got to remember to trust my ears over everything else :)

Anyhow, encouraged by your note I took a magnifying glass and light to the trim opening and managed, after some contortion and considerable neck ache, to get sight of the slots in the screw heads and a small jeweller's cross-head did the trick (the heads seem able to take a straight too, as you stated, since one of the cross slots is full. Anyhow, the contact was clean with this and a couple of small adjustments had the strobe sitting still and my peace of mind restored. Might be time to get the new power supply for the table -- but for now I'm happy. Yes, the SME 20 is a beautiful design, everything just sort of works.
