Hi — I pulled what appears to be a 17b out of the attic a while back. Chassis rough, cabinet even rougher. (This set was an antique when I was in the high school radio club 45 years ago.).
After lurking here for a couple of weeks, downloading some schematics, and refreshing my memory as to what a superheat receiver is, now I have some total newbie questions:
How do I know what a “Type 42” tube (for example) is?
In a cardboard box I found a Cunningham CX-326 and National Union NX-171A and some te others, what “type(s)” are these?
