I have a model F and yes it was tricky to get working. The new beam spring (v2, metal case) was a breeze to set up (just put the caps on, mx style) and works flawlessly.

The keyboard sits very high and it is a very different feel (long travel, very loud) but it is unlike any other keyboard I have used and very inexpensive compared to used original beam springs.

Worth a look if you are a retro keyboard enthusiast.
