Unless otherwise specified, resistance values are in ohms, L/2

watt, and I0% tolerance. Capacitance values smaller than I

are in microfarads (mfd); values greater than t are in pico-

farads (pF.

) .

The terminal numbering of rotary switches and printed circuit

board wires is for reference only.

A11 voltages are measured under the following conditions:

1. Use of an lO-megohm input impedance VTVMvoltmeter.

2. AII voltages !LO% with respect to chassis ground.

3. No signal at input terminals.

4. AC input at LL7 volts, 50/60 cycles.
