NOTES:
1.
For model CA50-28, the multiplier stage is not used. Therefore, the following changes are made in pc
board wiring for this model only:
These parts are not used on this model: R13, Q4, C21, R14, L7, C23, C24, C25, and L8.
A jumper should be installed in place of Q4 base-collector. A second jumper should be installed in place
of C24. This effectively connects the junction of L6/C20 to C8. When wiring is finished, check the circuit
on the pc board to assure yourself that there is a complete circuit bypassing the usual multiplier stage.
A 10K resistor (R16) should be soldered to the pad normally used for the hot lead of L8. The resistor
should stand up on the pc board vertically, and the top lead should be trimmed to 1/8 inch to be used as a
test point.
To peak oscillator coil L6, it is necessary to use an rf probe and voltmeter or an oscilloscope. Connect
probe to the top of test point resistor R16, and peak L6 as otherwise stated in step (e.) of alignment instruc-
tions.

.001µF capacitor may be marked "102", "1nM", or "1nK".
