    I like the PHOTON PHUZZ & beginning the process of parts order towards build.

    Has anyone attempted using a BC108 in place of a BC109 for Q1?

    Directions state both sound great, I wasn’t certain that the pinout is identical?

    Also has anyone tried a different diode for this build other than 1N4739 for D1?

    I don’t think the transistor change is going to make much of a difference.  I tried different transistors and found that higher gain transistors of around 400 hfe or greater worked better.

    Pink Jimi Photon stated that the diode should not make that much of a difference.  Look up the thread on “zener diode question” and you will have a more full explanation.
