Install ceramic and polystyrene capacitors in Sec-
tion 3 of the circuit board as follows:

I ) C22: 1000 pF polystyrene.
( ] C23: 1000 pF polystyrene.
( ) C51: .001 "F (102) glass ceramic.
[ ] C15: 1500 pF polystyrene.
( ) C47: .001 F (102] glass ceramic.

[ ) Solder the leads to the foil and cut off the ex-
cess lead lengths.

Install ceramic and polystyrene capacitors in Sec-
tion 4 of the circuit board as follows:

( ) 025: 1000 pF polystyrene.
( ] C55: 1000 pF polystyrene.
( ) C53: .001 uF (102) glass ceramic.
( ) C45: .001 uF (102) glass ceramic.

( ) Solder the leads to the foil and cut off the ex-
cess lead lengths.

Install ceramic and polystyrene capacitors in Sec-
tion 5 of the circuit board as follows:

( ] C26: 1000 pF polystyrene.
( ) C56: 68 pF ceramic.
[ ) C48: .001 pF (102) glass ceramic.

( ) Solder the leads to the foil and cut off the ex-
cess lead lengths.

Install components in Section 6 of the circuit board
as follows:

( ] C27: 1000 pF polystyrene capacitor.
( ) C28: 1000 pF polystyrene capacitor.
( ) 029: 1000 pF polystyrene capacitor.

( ) Solder the leads to the foil and cut off the ex-
cess lead lengths.

[ ) Q1: Install an MPSAZO transistor (#417-801)
in the circuit board at Q1. Position the transis-
tor so the flat side is over the outline of the
flat on the circuit board. Then start the leads
into their corresponding holes in the circuit
board. Position the transistor 1/4 above the
circuit board. Then solder the leads to the foil
and cut off any excess lead lengths.

( ] C312100 pF (100K) ceramic capacitor.

( ) Rs: 1.2 0., 2-watt, 10% (brn-red-gold-silv) re-
sistor.

( ) C33: .1 ptF [104) glass ceramic capacitor.
( ) C37: .1 it]? (104) glass ceramic capacitor.
( ] C34: .01 uF (103] glass ceramic capacitor.

[ ) Solder the leads to the foil and cut off the ex-
cess lead lengths.
