REMOVAL OF SET
First remove chassis from its present case by iirst removing "B" batteries
and also "A" battery tray. Remove 2'screws on baffle inside case. Remove
screw from bottom of cabinet. Carefully slide out chassis. Take the new case
and with chassis outside the case note that one: of the wires from the Regaloop
in front cover is color coded. Solder this wire to the lug on top of variable
condenser, right hand side looking at it from rear. This is the oscillator section.
The remaining wire from the Regaloop should be soldered to the lug on the
terminal strip mounted on the variable condenser mounting bracket.
ALIGNMENT OF RECEIVER TO MATCH REGALOOP
_ Use a signal generator and output meter. Connect output meter to voice
coil leads on speaker. Make a loop consisting on one or two turns of wire and
connect ends to signal generator, and place "loop" near enough to the Regaloop
(located in front cover) to effect asignal transfer. Set signal generator to
1650 KC. Open variable condenser all the way so that rotor plates are entirely
out of stator plate assembly. Use a non-metalic screw driver and adjust oscillator
trimmer for maximum output, Now set signal generator to 1500 KC-tune
receiver to 1500 KC and adjust the remaining R.F. trimmer for maximum
Your chassis is now tuned to the Regaloop in the new case. Place the chassis
back in the case and install batteries.
