CIRCUIT DESCRIPTION
300-VOLT LINE
To minimizevariationsandrippleinthe line, a
silicon bridgerectifier circuit andchalkinput
system areemployedforthe300-voltB line.
210-VOLT LINE
Resistors areplacedinseriesbetweenthe300-volt
line andthe210-voltlineforthepurposeof
droppingthevoltage.
150-VOLT LINE
If the150-voltlinevoltagedropsduetoa varia-
tion ofload,thegridvoltageonthetriodsideof
V2oi 6BM8 will alsodrop. This causestheplate
currenttodecrease,sincethecathodvoltageis
fixed.
When theplatecurrentdecreases,thevoltage drop
acrosstheR201470Kftbecomesless, while the
platevoltage tends torise.Accordingly,thegrid
biasonthe pentode sideof 6BM8 tends tode-
crease,therebystabilizingthe150-volt output at
theoperatingpoint. This output voltagecanbe
varied byadjustingthe VRi half-fixed resistor.
(-) C LINE FOR BIAS
The half-wavecurrentissuppliedtothe(-)C line
for thebiasthrougha silicon diode.
12.6-VOLT LINE
To supplyheatervoltages,thepowertransformer
hastwo12.6-voltsecondarywindings; that is, one
for the final S2001 x 2 line exclusively forthe
transceiver andtheotherforothervacuumtubes.
Taking intoconsiderationa possiblevoltage drop
atthepowersupplycordbetweenthePS-510and
the TS-510, thetransformerisprovided with two
13.5-volt windings.
63-VOLT LINE
A 6.3-voltwindingisusedforheatingthe 6BM8.
To preventthebreakageoftheinsulationbetween
the cathode heaters,thiswindingisapplied with a
voltageof+150V.
SPEAKER TERMINALS
The powersupply jack incorporatesspeakerline
terminals. Theon-offpower switch isattachedto
thetransceiver.Partofthelead wire tothetrans-
formerprimarywindingisconnected with the
powersupplysocket. This enablestheoperatorto

1. Howto Take Outthe Chassis
Remove thetwoflat-head boltsfromthetop
of theenclosure,fourdecorativeboltsfrom
its sides,andsevenlockingboltsfromthe
bottom. Then thechassiscanbedrawnout
from theenclosuretowardyou.The Hyzex
legs neednotberemovedfromthechassis.

dition. Then adjustthevoltageto150volts
by turningthe half-fixed resistor VRi located
onthebackofthe PS-510.
