Thanks!
Do I need the SCR? My (mainly) use is to drive a wireless trigger.
If I attach a flash unit directly to the pc port do I need this SCR?

This SCR mod is just to trigger old flash units that handle high voltage on hot shoe and PC Sync port.

If you will trigger only a wireless trigger all is ok, just a transistor or a single optocoupler.
