[Moon-net] Advise on bifilar choke for 8877 filament

[Jerry Kleker]

Hi Ed,

I checked McMaster Carr and they have 50 foot spools of #12 enameled
for $18.35. The part number is 7588K25

GL es 73,

  I'm winding coils for my 2m-8877 PA (classic-W6PO design) and am 
  wondering if I might use insulated #12 solid copper wire in place of 
  enameled #12?  I will have to buy a complete spool of the enameled 
  wire mail-order if that is necessary.  It appears to me that 
  insulation in the bifilar choke is for dc voltage so insulation would 
  likely only shift the inductance some.  I can check that with a MFJ-269.

  So what's the opinion on this?
  The remaining coils are all #14 copper which can be found locally.
