[Kenwood] Re: Kenwood Digest, TS-520 VFO jumper plug pin-out

[J. Michael Thurman]

Well, I replaced the MPC resistors with standard carbon .47K 1W 
resistors.  The difference: audio distortion.   That "Kenwood" sound 
seems to require MPC's.

  Fortunately, I found that the real problem in my AF board wasn't 
the resistors.  It was the electrolytic cap just downstream of the resistors.
