[Boatanchors] B&W 850A Doc(s) needed

[Rbethman]

Gary,

I see the connection on the rear of the 850A that goes to the beginning 
of the front coil, I see the switch pads for band switching., AND I have 
and see the 10 mtr strap coil on the rear ceramic plate.

In a PI network, the beginning of the coil comes off the tuning VAR cap, 
and the END of the output of the last part of the switched coil goes to 
the Loading coil - Correct?

I also do NOT have the escutcheon to display the band positions.

Before I go off the DEEP end, I want to be reasonably sure NOT to let 
the "smoke" out of a 3+KV circuit.

In past jobs I have experienced 4160VAC and 13,800VAC loose in and over 
the cover of an enclosure.

I SINCERELY do NOT wish to repeat these incidents.  I find it preferable 
to KNOW more before I dig in and wire things up!

Would love to find the escutcheon for a B&W 850A. to assist forgetfulness!

I'm using a Harris 3KV to 4KV power supply.  I also have an extra one.

I'm off down the path to building a 4-1000A GG amplifier.

Prior to this I have only built a pair of 813s and a pair of 572Bs.

I'm going to use either a DX-60B and/or An Apache to drive "Sasquatch"!

I also run a pair of BC-610s.

I just don't want to "Screw the pooch"!
