The Michell Tender feet are supplied in sets of three in standard size or the larger cones (40mm height) and 12mm 'Flattened' types. They are precision machined aluminium cone supports 35mm base diameter. (Though inteneded for use in threes a fourth cone could be positioned under a pre-amp with no slack fit anywhere:impressive!) I would suggest the shallow ones are best suited to loudspeakers the 62 Degree ones to components such as pre-amp/psu CD player and possibly turntable.
