NOTES:
1)

B(+) power supply
2)
=
Signal path
»>
Rec. path
3)
The voltage is the reference value measured with a tester
(20 k-ohms/V DC) when there are no signals.
An asterisk
(*) indicates that the value was measured
with a vacuum-tube voltmeter during recording.
4)
Resistors with
no designation
have a rated
power of
%W and a tolerance of +5%.
5)
Capacitors with no designation have a dielectric strength
of less than 50WV.
6)
Ceramic capacitor symbols:
Q, t For temperature compensation (SL)
dh High dielectric constant system (YY)
+
High dielectric constant system (YP, YZ)
7)
The only capacitor tolerances
indicated are +2%
(G),
+5% (J) and +10% (K).
