Hi Lee, I had the same reservations, vis a vis, winding the toroids, and the advice you have received is spot on.
There is an additional solution, however, and that is to purchase a complete set (for each kit) of pre-wound toroids. I went this direction and the product was absolutely first rate. I did check each one as I installed it, and they were uniformly outstanding. If you have the time and patience, wind them yourself, if either time or patience is a restricting resource, buy them. Here is the link: http://www.elecraft.com/Apps/ToroidGuy/toroidguy_prewound_toroids.htm As you can see from the link, elecraft endorses (that may not be the correct term for their relationship, but they at least provide the information to prospective buyers).

As for zapping ICs, practice safe ESD techniques at the workbench. If you have a wrist strap available, use it when handling ESD Sensitive devices, or even better, also use a properly grounded (through a high value resistance) anti-static mat on the workbench. At a minimum, follow the instructions in the manual to 'touch an unpainted metal surface' before handling these devices. The real key to safe ESD practice is to keep everything at the same potential - before handling ICs, I make sure everything is on my antistatic mat - that includes the circuit board, IC (still in its anti-static foam), any tools I will use, as well as both hands, and if I have any doubt or the air is particularly dry, I put the wrist strap on too. 73, Don W3FPR > -----Original Message----- > > My main worry is with the stripping process.
