Default Hammarlund HX50 6DQ5 Plate choke question.

Gents,
I am restoring an HX50 for a friend. It appears that someone has modified
L115 (wrapped around R181, 47 ohm 1w) by altering the amount of turns in two
ways.

1) Inspection of the solder ends where the inductor (L115) is soldered to
the resistor's lead wire appears to have been changed. Extra overlapping
wire, as though someone shortened the total length of the inductor's wire,
has been adjusted and soldered to the resistor's lead wires.

2) Solder blobs have been placed on the inductor as to short out two of the
turns.

Please see pictures at the bottom of page:
http://www.ppinyot.com/hammarlund.htm. Sorry for the fuzzy blow ups. I do
not have a close up Macro lens available at this time.

Can someone tell me the proper quantity of turns the inductor L115 should
have, wrapped around R181, 47ohm 1w resistor? And/or send me a picture of
an operational unit?

It would be a big help to have this worked out before +700v, alignment and
calibration.

Thanks,
Paul
