This is an AM Broadcast only Transoceanic style AC/DC portable. I uses
the same tube line up as the Transoceanic with out the Ballast tube. The
1L6 is used in this chassis. I tried the 1S5 with out luck. The
radio was dead. When Pin 5 was lifted the radio received well under 1000
KHz. Above that dial frequency it became increasingly full of
"birdies", At 1600 the radio only produced static.
So a good 1L6 is in this chassis.
When comparing the circuits for a TO and this radio one can see significant
differences. The least of which is the oscillator coil has less sections
in this radio. That is where the 1S5 incompatibility come in to
play.
This is a beautiful example of the Zenith portable AM radio of its
time.
Brasso, Novice 1, 2 & 3 polish and a Dremel cloth wheel with rouge
brought out the original shine.
Treated exterior with cleaner and preservative. New Power cord.
The handle and knobs were cleaned and polished with Brasso. Yep
Brasso.
Rear.
Clean chassis.
The power switch in part of the door hinge. When closed the power
is off.
Restored chassis.
See the silicon diode and new white wire wound dropping resistor
replacing the Selenium rectifier.
This unit was successfully tested on a Transoceanic
replica battery.
