[Boatanchors] KW TS-520 rotary switch repair

[hwhall at compuserve.com]

It looked to me like in the linked SE version manual and the S version manual the S5 switch was part S01-3401-05.

Hard to find a good SM scan, but looks like in the parts list its  [S5] 
Rotary
switch, Final part no. S10-1101-05

Seems to be a shorting type switch on S5-2 and 3 while section 1 is just a 
SPST.

In the he 520SE schematic it shows they are used, but these are not 
connected,
and never have been as they are tarnished with black film.

Page 7 of the scan shows the S5 switch

This is a SM for the plain 520, and on pg 24 they show the PA diagram but
S5 has 5 sections

http://www.qrzcq.com/pub/RADIO_MANUALS/KENWOOD/KENWOOD--TS-520S-Service-Manual.pdf

Then on the schematics near the very end of the manual, I see only 4 
sections.

I guess the SPST section is common to both models, but its definately not 
got any wires
on that section on the one I have.

Perhaps if we see the switch schematic, someone may have a switch from 
somewhere that performs a similar function.
