Here's the data sheet on the 10mm round Piher trimmers. They're the kind you see in the Phase 90 reissues and others. I think they'd make nice trimmers for the ROG perf projects. They have a nice, small footprint. The data sheet has a pic, they would be the two outside trimmers on the bottom row.

This is the entire page of Piher 10mm 100k trimmers.

I would like someone to double check the data sheet for me. It should be correct for a 10mm horizontal mount (laydown), slotted screwdriver vertical adjust, 100k lin., with a 20% tolorance. I'm not sure of the lug spacing in regards to the standard perfboard everyone uses. Hope this helps or is interesting. Thanks.

I know it doesn't help our friends in other countries, but I've just been buying the Radio Shack trimpots. They've got a nice small footprint, and aren't that expensive, and have held up well.

I used them without any problems in my thunderchief.
Used the screwdriver adjustable ones.

I like the ones that 'face up'...I've used ones that face 'over' and built limited access around it to the point I had to use needle nosers 'repeatedly' to get from one side of the range to the other...
 I like the phillips head drive ones, little orange circles with the + facing are easy to 'hit with the screwdriver and adjust...I don't have to think about which way to put them in other than enough space to make connections.

These are the ones that face up. I like em' better too.
