manufacture (blue)

************ Hi-Power Pi-Coil + Bandswitch assembly **************

The Pi coil is wound in 3 co-linear sections:

   24 T #8 copper wire  6" long on a 3½" diameter ceramic form -- my
calulations show 22uH

   6T ¼" Copper tubing  2" long 3" diameter -- another 2.5 uH

   & 6T ¼ Copper tubing 2½" diameter by 2½" long -- 1.8 uH

   Including the end stuff this assembly is about 14" long overall so, it
isn't for a small amp.

   The copper is tarnished, but not too bad -- a quick dip in Tarn-X or
vinegar should clean it up.

  The bandswitch is 6 postion -- very heavy duty.  The contacts are 3/8"
diameter (and about the same hi!) and the rotor contact is a pair of 3/8"
wide strips.  It has a nice roller detent on the rotor.  This was
obviously originally some commercial switch but, the components have been
remounted to a large (6" x 8") sheet of plexiglass.   Four of the 6 taps
are currently connected to the coils with 1/4 wide strap.   

  Finally, there are three large 6" ceramic and glass standoffs that
support the coil assembly.  $50

********************** Fixed Coils *******************************

55 uH silver plated edge wound .200 x .05 buss wire.   5" diameter by 10"
long overall  $30

20uH plated #14 wire on 2½" ceramic form; aged but unused  $5 ea. 

Filament choke for GG amp.  Bifilar wound #10 wire on ½" dia. by 7½" long
ferrite form.  Used, good condx -- $15


**************  MISCELLANEOUS *****************

Square D, size 2, two pole, contactor rated at 50 amps (600 V max).  The
coil is 120VAC -- $20 used

Johnson 154-506 Dual 153pF 3KV air variable used, good  $20ea (2
available)

Hammarlund NZ-10 Neutralizing capacitors, shiny NOS,  $25 pair

Ohmite 75K 175W resistors w/ mtng. brackets, used.  $5 ea

Westinghouse 6-1-1B/1N1188 3 Phase 600V 35 Amp rectifier assembly 
with heatsink.  Unused but, tarnished from long storage  $10.

Collins 672-2110-00,  7.5VCT 24A Filament Xfrmr  210/220/230/240/250
Primary (no 110!) -- One
 of the 7.5V terminals is broken off but, the wire is accessable in the
potting.
FREE!!! (plus shipping) w/$25 purchase from this list.
