IC 4051 on TSB

2013-10-22 by <martinjboisvert@...>

Greetings,

I am in the process of changing out the IC 4051's on the TSB boards and during the de soldering process a trace got sucked up! It is the trace that connects Pin 12 on IC4. Is it possible that Pin12 is not used as it does not seem to be connected to anything on either side of the board!?!

Thanks

Martin
