[Amps] B&W plate choke

[Carcia, Francis A HS]

The 802 is just a number of close wound turns at the bottom of the form
to increase the inductance. I have never measured the series resonance
but my old 4-1000A rig was converted to cover 160 meters through 10 meters
and my friend who has it now has no problems. (knock on wood)  gfz

I believe Dick Bryd, N4UQ still has a B&W upgrade program where he takes 
your #800 in on trade and then issues out a re-wound #802 choke (on old #800

ceramic cores) from his bench inventory.  I used his chokes for my Alpha 77 
and 70V, and I was very pleased with his work, pricing, and turn-around 
time.
