2. Sockets connections are shown as bottom, views.
3. Measured values are from socket pin to com-
mon negative unless otherwise stated.
4. Line voltage maintained at 117 volts for
voltage readings.
5. Front panels controls set at maximum.
6. Where readings may vary according to the
setting of the service controls, both
minimum and maximum readings are given.
ALIGNMENT INSTRUCTIONSPRE-ALIGNMENT INSTRUCTIONS-READ CAREFULLY BEFORE ATTEMPTING ALIGNMENT
To eliminate shock hazard, disable high voltage by unsoldering the lead feeding B+ to highvoltage oscillator tube 12SN7 (V18). Use an isolation transformer when available as one sideof the line is connected to chassis.

RF OSCILLATOR ALIGNMENTThe RF Amplifier and mixer lines are pre-set at the factory and due to their stability normally
do not require adjustment. Since Channel 2 Oscillator Coll is in parallel with all other osc.colls at their respective channels. Channel 2 must be aligned f irst . If Channel 2 Is readjustedat any time, it will be necessary to realign all the other channels.
