use #16, #18, or #20 teflon wire for windings

typical transformers are wound 4:1 but I have seen 5:1 and 3:1
input and output transformers are typically identical except the outputs are usually
twice as long (use four beads instead of two) and input use #20 silver/teflon wire
(wound bifilar) but outputs use #16-18

typical B-C is a 100ohm 2w (non inductive) resistor in series with a 0.01uF ceramic
(probably should use dipped mica or other higher voltage rating)

typical B-ground is 10ohm 1/2w (inductive ok)

typical C-ground is 100pF dipped mica

typical C-C is 430pF dipped mica

typical C-E is 330pF dipped mica

if only one pill is used, B-ground with two 0.01uF ceramic in parallel.
do the same for C-ground
may need to change C-C to 500pF

typical input splitters use 1/2" torroid
wind with 5-7 turns #20 silver/teflon wire
span with 100ohm 1/2w non inductive resistor

typical output combiners use 1" torroid wound straight or bifilar,
using 5-7 turns #16 or 18 silver/teflon wire
span with 100ohm 2w non inductive resistor
resistor can be routed through torroid to save space

input and output tuning are typically accomplished with a pi network
feed signal through a 6-7 turn inductor made with #12 enamel wire,
wound around a 1/2" form.  pack turns, do not space.
capacitor on output to ground is typically 68 or 75pF dipped mica
capacitor on input to ground is typically 45-200pF mica compression
(GMA 80400?)  (trimmer should have adjustment screw on ground side)

Bias is typically done by using a generic 1N4001 etc thermally linked to
the heat sink, cathode grounded.  Anode is fed with +12v through 80-100ohm
of resistance at 

Use of output transformers that are built with N43 beads may lead to saturation
at higher power levels.  Four standard beads saturate at around 100w. Changing
to N61 beads may improve output.  Longer N43 beads may be used instead,
four doube-length N43 beads make a transformer that saturates at 1kw.  For
output from a pair of 2879, using two large and two small beads is recommended,
for each pair of pills in a ganged amplifier.
