"Have no sidetone on a K2 that was just modified for the amp.  I have

unkeyed."

Remember the mod you did on the Control board by cutting the trace from
pin 25 of U6, and wiring the gate of Q5 to pin 4 of U8 (page 51 of the
KPA100 manual)?

To make the sidetone audible, you have to go to activate menu item ST L
and tap DISPLAY to change the sidetone source to U8-4.
