0 Voltages are dc with respect to ground unless otherwise
noted.

a Readings are taken under no-signal (detunedl conditions
with a VOM i20kn/VI.
i V): REG

0 Voltage variations may be noted due to normal pro-
duction tolerances.

I Transistor base-emitter voltages are measured on the 2.5V
range.

0 Total current is measured with no cassette installed.
