Group 1: Power, Audio and Keyer stages.
NOTES:
Do not install the ICs into the sockets until after the initial smoke test. R11 and R2 are 1% resistors, so have four color bands
for the value, instead of three for the 5% resistors. They also may have a blue body color, instead of tan. On C9, C13 and C22
the long lead is + and the negative lead side is marked with a black strip on the cap body. Diodes D1 and D2 are installed "back
to back", therefore, the black band on the diode (cathode end) should be facing in opposite directions from each other.
