I have found a source for the SSL style Sifam knobs in the USA if anyone is looking for them. Their US distributor sells them: selcoproducts.com
I ordered 20 knobs and caps through them for $2.50 per knob and $0.55 per cap, plus they threw in a tightening tool for free.
The exact model is S151-025-GRY, with blue caps. They are 6.35mm shaft, which should fit the Lorlin switches and Alpha pots used in the project.
Hope that helps someone.![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
