It should be:

   -               AC
    \              /
     +----|>]-----+
     |            |
     |            |
     -            -
     V            V
     -            -
     |            |
     |            |
     +----[>|-----+
    /              \
   AC               +

Before anyone attempts to do anything based on the original. (After all
those years in school learning all the nice things about semiconductors
and such shouldn't be wasted.)

Hugo.

PS: Modern classical music sounds much like they suffer from a bad
semiconductor.
