Funny you should mention the "1812 Overture." I happened to be in the KDFC 
studios on top of Mt. Beacon for Steve Waldee's farewell show (somewhere 
around midnight." In an unusual move for KDFC, Steve played some vinyl live 
to air (and also did a bit of "personality radio"--a definite 
format-breaker for KDFC) , including the infamous Overture. Steve and I 
discussed whether it was worth the risk, and Steve finally went for it. Lo 
and behold, the first cannon shot threw the stylus entirely out of the 
groove and the tone arm went skittering across the record...all live on 
air. IIRC, they had Stanton cartridges installed, and they just couldn't 
track that kind of stuff. The Shure V15 of that era, of course, had no 
problems.

Now that I've had a little more reminiscing time, I think it was called the 
"Top Level." Being a pre-emphasized clipper, it was intended for FM only.
