___ Install the .01uf 50v 8 pin SIP Capacitors, C11, 17, 19-22. Pin one is marked on the PC board
with a box, and marked on the SIP capacitor with a line.
___ Install the 78L05, U4. Note the orientation.
___ Install the 2N3904 transistor, Q1-2. Note the correct orientation.
___ Install the variable resistors, 100K pots, R22-23.
___ Install the trimmer capacitor C1. Note that C1 has two pins that are common (connected). They
should line up with the two holes on the PC board that are connected together with a trace on the
bottom.
___ Install the socket for U1, 52 Pin PLCC socket. Note the orientation of the socket. The flattened
corner on the socket matches silk screen. Do not install U1 (the 68HC11) until later.
___ Install the socket for U2, 44 Pin PLCC socket. Note the orientation of the socket. The flattened
corner on the socket matches silk screen. Do not install U2 (the UCNQ5818) until later.
___ Install the socket for U3, 8 Pin DIP socket. Note the orientation of the socket. The notched edge
on the socket matches silk screen. Do not install U3 (the LN311) until later.
___ Install the ceramic capacitors, C2 and 14 100pf 1KV, C15-16 & C25-27 10pf 500V, C28 39pf
500V, C29 82pf 500V, C30 150pf 1KV, C31 330pf 1KV, C32-34 680pf 1KV.
