Philco 70 with shortwave
#2

Congratulations! Icon_thumbup

Unless it was removed, there is a very thick coaxial cable which should protrude from the SW converter chassis.

Connect the center conductor to the ANT terminal on the 70, and the outer shield of the cable to the GND terminal on the 70.

Connect your antenna and ground to the appropriate terminals on the converter (instead of on the 70 itself).

To use the converter:

Tune your 70 to 100 on the dial (1000 kc).

Turn the converter on. You'll have to wait for the converter's tubes to warm up. Once they do, leave your 70's dial at 100 and do your tuning with the converter.

When the converter is turned off, the antenna and ground are bypassed from the converter to the radio. When you turn the converter on, it not only applies power to the converter, it switches antenna and ground to the converter.
