Mine tuned up by the book (more fun than the modern "dial'n'talk"). However,
if your serial number is below 5446, the driver preselector may peak in a
slightly different spot for transmit and receive. If yours is in this
category, there was a mod that may have been done - look for a 3-lug
terminal strip soldered to one of the shields between two of the PC boards
in the bandswitch assembly. (Info from Chuck Penson's "Heathkit: A Guide to
the Amateur Radio Products", Electric Radio Press, Inc., 1995).

There's also been a little talk on this list regarding the use of the old
rigs on the higher line voltage we see today, and that you might want to use
a variac or some other means of lowering your line to 110VAC.
