K2 build question - stem bumper on L33

Hi all,

Slowly but surely K2 #6773 is coming together. I've noticed that the stem bumper included for the L33 toroid actually protrudes through the middle a small distance. This will elevate R116 above the toroid, which is not what the instructions (page 61, first column, first instruction) suggest. I'm a bit worried about R116 atop the stem bumper being taller than the standoffs to the bottom of the case and thus getting mashed when the case is assembled.

I could cut the center of the stem bumper to shorten it, but that seems drastic... Any ideas?

Thanks
Joe

Joe,

Cutting the tip off the stem bumper is not drastic at all, and is
exactly what is called for in the instructions. See the first step on
page 60 of the K2 manual in the right column.

With the stem bumper cut, you can then press down on the resistor body
to tighten the fastenings for L33. Note that the high value resistor is
really treated as an insulator - its only purpose is to secure L33 and
provide convenient points for soldering the wires of L33.

Ah yes. Thank you Don. Clearly I've been working too far past my bed time.
