[ARC5] B&W 350 Phase Shift Network for W2EWL SSB rig

[millerke6f at aol.com]

 Here is the one used in the HEATHKIT  SB-10 SSB adaptor for what it's worth.   I've duplicated this guy more than once over the years and stuff them in old metal can octal tube cases.  Work like champsand modern .1 percent resistors at pennies each and NPO smt caps work well also.

  I have a Lakeshore Bandmaster II-B, the one with the VFO. I don't know whether its size + weight and the not sane number of my other projects will dictate i sell it. I also have an audio phase shift network in a little package like a metal tube. I don't remember the maker right now - this is what happens apparently when the % of memory space used approaches the capacity - but you will know it anyway. I was wondering about the longterm stsbility of the 1% resistors in the audio phase shift networks. Knowing about old - style carbon resistors, i am not optimistic.-Hue Miller
