My EAC s/n 204 R-390A isn't used for DX anymore, but I fire it up now and then to make sure that it works properly. And it always does. This time, I connected a pair of Logitech active speakers to the audio and line out connections.
Using the Lankford-designed manual AM sync I can enjoy distortion-free reception with the R-390A. It is enabled by switching the BFO switch on. Tune the Pitch control to obtain zero beat. At the time I took the photo, I was tuned to Radio Romania's German service. The radio on top is a 1950's Radionette. Works perfectly too, except there's no light in the magic eye.
