All capacitors
are
in wF unless
otherwise
noted.
pF = uwuF. 50 WV
or less are not indicated except
for electrolytics.
All
resistors
are
in
ohms,
"%W
unless
otherwise
noted. kQ = 10002, MQ = 1000kN
All variable and adjustable resistors have character-
istic curve B, unless otherwise noted.
4
: internal component.
PME
+ B+ bus.
[]
: panel designation.
(_____| : adjustment for repair.
Voltages
are dc, and
are measured
when
plugging
microphone
unit
into
MIC
input jack in ac ope-
ration condition.
Readings
are
taken
under
no
signa!
conditions
with a VOM (20k2/V).
Voltage
variations
may
be
noted
due
to
normal
production tolerances.
: B+ pattern.
DC resistance measurements are with coils connect-
ed
on
the
circuit
board,
and
are
approximate.
