[Elecraft] K2 Build: Requesting Tips and Tricks

[GaryK9GS]

Hi Fred,
It's called a sequencer.  Individual reels of tape and reel axial parts are loaded in the sequencer.  So there would be an entire reel of 10k resistors, a separate reel of 100k, separate reel of diodes, etc.
The sequencer then removes the parts from the tape and creates a new tape with the parts in the proper order and count.  The sequencer my company used to have would also measure the value of the part and reject it if it wasn't in the tolerance window.
I hope that all makes sense...
Surface mount is oh so much easier.  We have 9 surface mount lines and rarely use the axial through hole inserter these days.

Its been 15 years or so [K2 S/N 4398] but my resistors were taped in the 
order of insertion.  If yours are, don't remove them before needed.  I 
measured each of mine as I was about to insert it, and all were 
correct.  I can see the colors, I just can't name them so this was a 
huge gift from Elecraft. Benton Harbor just sent a bag, but of course 
auto-insertion equipment hadn't been invented then either. [:-)  I've 
always wondered how the machine that tapes them works.

I recorded every mod, change and alternate part over the 10 years and essentially wrote a new updated assembly manual. Bought all the add on options. Bought new firm ware that I never got to use and bought new again at the finish. Turned it on and guess what, no issues. Somehow I like the way it sounds, maybe better than the K3...

I had 12 I think which was more than enough, about 4 inches diameter and a couple of inches deep. Keeping the lids on and marked with the contents helped keep from them scattering from a careless movement or other accident.

Right now my biggest problem as I see it, is how to organize all the caps and resistors to make the build go smooth and relatively quick.  At any rate, all suggestions are welcome.
