Lefty,
This is a truely Superadio with it's wideband AM in operation. You can get the full AM +10kc/-10kc signal where all the good audio is. Most modern receivers chop this off with parts economy and give you the AM sound we are used to. FM is spot-on.
Now it is back on the market as the RCA RP7887 for around $45 at Amazon and others. Same vendor...new badge. A few searches for opinions seem to say the same thing as the GE version. Great sound etc. But it still has the problem of a mis-aligned AM dial scale. It can be off by quite a bit. 610kz may show as 680kz. There are web sites showing how to re-align it, but taking the case apart can be a problem. It may never go back together.
But now with HD radio (not High Def but Hybrid Digital) being transmitted during daylight hours by many stations, the outer 5kz of the full signal on either side of center is the digital realm. There goes half of your wide-band during the day. Night-time is still ok when the digital shuts down and where the best DX is anyway.
I would save the parts search and get a new one for a starter. $45 is a tank of gas anymore. And then I would start looking for the Superadio I and II. I prefer the II. They have real tuners, the III is a slug-coil. Any one of them sucks in signals from distant stations. And there is even a boom-box version with a casette player not promoted as a Superadio, but has the chassis and speakers. I found two dead ones of those for $2 total at a swap meet and swapped parts to make one work. Earphone connector board as I remember.
