[Boatanchors] What are they?

Sounds very interesting.

How did they pack a 5763/6146 combination with the full RF network and
power supply into a 6x8x5 box ?? Being 80m and 40m it's probably band
imaging. The three 6U8s receiver sounds like a Simple-X derivative
somewhere in the mid 60s timeframe. The third unit may be the power
supply and speaker for the receiver. Pictures ?
