That is true. I received my SITs yesterday and they came with the isolation sheet and 5 bushing rings. The SITs were matched within 0.1V, 2.27V & 2.17V respectively, if you can trust prss1701's measurements. Some assembly is required as the bushing is about 2.5mm longer than the SIT is wide.

I Have these in my next Mouser order for mounting after measuring THF several times with digital calipers (out of paranoia). They will be nice and tight and fully insulate the mounting ear holes while allowing me to use 6-32 stainless screws to mount these hockey pucks.

These are the pads I settled for.

@ Del...nice to see someone else doing chassis work from scratch too. Haven’t taken any pics but the aluminum chips are flying here too ;)

Has there been a BOM written up for the Sissy that we need to come up with ourselves assuming our THF are within Zen’s Kosher range for this project?

My own measurements showed Prasi's to be spot on and the three devices I bought are all a gnat's whisker apart.
