Greetings,</p>

I am happy to report that jimmywilliams, organsR4me, Andy and anyone who has posted on this subject have been very helpful. I replaced a small npn transistor and a couple of diodes in the percussion section of the board and now no extraneous cipher. My first replacement was an A# keyer in the AOC for the upper manual since that was the particular frequency of the cipher. This did not cure the cipher but maybe I have averted another problem for later. Again, thanks so much.</p>
