Mining123-
Peter helped me to put 12BH7 design (and most other PCB mount tube socket bases) in fritzing library. Here is list of vacuum tube bases that Peter helped me with to add to the fritzing library:
7 pin
8 pin octal
9 pin noval
9 pin magnoval / novar
12 pin compactron
The 12BH7 uses 9 pin noval. Link below to the location thread:
Vacuum tube sockets Layout. Specifically: tube-socket-9pin.fzpz (3.9 KB)
Locations of other mentioned tube footprints, per development threads, are tedious to discover-
Hopefully Peter could guide you to a library where the .fzpz files of other sockets are listed.
Welcome aboard to fritzing, the customer service here is impeccable.
