Nice job but for one thing, it's too close to the wall to be rotatable. That comes in handy for squashing QRM considering the figure 8 pattern has deep nulls off the edges of the loop. An interesting coincidence, I have the same preamp. Oh, I like those old radios, my very first was an All American 5 in a Bakelite case. My discovery of stations between stations at night started me on the road to SWLing and eventually Amateur Radio.
