The BC-348 was the first usable receiver I had when I was a novice. My scoutmaster and Elmer, K2EAW, bought a half a dozen of them in a surplus auction and we built 120 vac power supplies for them under his guidance and he loaned them out to all the kids in the troop who were interested in radio. I had mine paired up with a 50C5 one tube transmitter on a piece of pine board - a copy of the transmitter on the cover of an Electronics Illustrated magazine and my first totally home built project.
I recall the 348 as not being all that selective for CW in the 40 meter novice band, but looks like for AM phone it would be pretty good. I used to enjoy tuning around the low band with it and listening to the aircraft beacons. I remember the feel of the dial.
That transmitter was kinda scary. No transformer. Built point to point between brass nails driven into the board. It called for a 400 ohm, 20 watt wirewound resistor in series with the 50 volt filament. I didn't have one of those, but I made up an array of random junquebox resistors that totalled 400 ohms more or less, but I doubt I had 20 watts dissipation and it certainly wasn't evenly distributed. One evening when I plugged it in, one of the resistors popped and acted like a roman candle and started spewing flame and sparks onto the curtains around the window that the desk was in front of. I think that was the first time my mom threw all the ham gear out the second floor bedroom window. Fortunately it had been raining and the ground was soft...
The BC348 took the landing fine. I suspect it had seen worse.
