Envelope generator PCBs ordered

I ordered some prototype envelope generator PCBs this weekend. I'm excited to get them in to try.If they work fine, I'll buy several more for the modular.

The PCB is labeled for BC550 and BC560 transistors, but I will probably use the original 2N5172s and 2N5138s to stay authentic. For the second run, I might change the package to reflect the pinout for the vintage parts.
