I also have a BC 348 "R" in need of some work. (A lot of work?) I picked it up at a hamfest for $20. One of those deals where the radio was no longer original, had holes drilled in the front panel and was missing screws to hold it all together lol. I thought it would be good for parts, but I actually got the thing going again. So now there's no turning back right? lol. Someone installed additional controls to the front panel. One is an RF gain control and the back half of the original volume control ( double gang type) was separated resulting in another new adjustable control installed on the front panel. So now it has dual volume controls ! LOL. Actually the circuit itself has something to do with the AVC / MVC. The original MVC / AVC "handle switch" is missing. Just a hole there now but oddly a third hole was drilled to install an on/ off toggle switch for power? I think I would have used the existing hole where the MVC/AVC control switch used to exist myself, but I suppose there's no point in trying to make sense out of it all. It has some kind of modified BFO and an additional tube and circuit was added inside. It's kind of an interesting mod I never ran into before on BC 348's. I thought about removing the "mods" plugging the holes and restoring it to its former ugliness, but it's missing some parts like the spindle rods used to secure it to the cabinet. The MVC / AVC control is missing and some of the control panel knobs are not original. Power supply and audio transformer is a bit of a botched job, (like many) but at least it actually works now. The wire to power the LM27 lamps was cut off and disconnected so the lights are there but they don't work. Wonder why that was done? I'll have to figure out where it's supposed to be connected. Anyways, I am just playing with this $20 BC 348R just the way it is for now. I put it back on the bench and played with it last night after reading your replies, but i'm not really sure what I am going to do with it exactly.
