[Hammarlund] Hammarlund chokes in SP-600

[rbethman]

I've chased down two chokes.  They come off the transformer output, 
taking off from the input to the rectifier.  They are in series, not 
counting the capacitors that are before, between, and after.  They in 
turn feed the 0A2 regulator.

In the J-11, they are L51 and L52.  The 0A2 is V-18.

I can only surmise that I have no problems.  I base this on having left 
it on and running for a week or weeks at a time.

The only problem I've developed, is the S-Meter.  I won't go into what 
"seems" to be the originating cause.  It was a dumb moment!  The 
movement works when I apply a voltage across the meter.  I've checked 
the meter rectifier tube, and went ahead and put in another just to be sure.

I guess I really need to take it out of the rack, and trace through 
carefully and see what the bloody devil is happening.
