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.
5. Front panel controls at:
