Exactly.

I built myself, from a kit, a good CB receiver (AM only). Among other 
things, I learned that part of the critical stuff is unobtainable. 
Specially the transformers and variable caps. A kit solves all that., 
but there are no more kits like that one.

And I did not have the instrumentation.

I lost the receiver, I think it was stolen.

Maybe this one:
