    I've got an old Univox FL-1000 Flanger/Delay which I'm fixing as a favor for someone.
    I've found a fried transistor already. But, I'm wondering if anyone has a schematic for this unit they'd be willing to share.
    I've not had luck finding one other than for sale. :)

    Thanks for that great link !

    The fried TR is a C536. I've got some coming. The circuit has a few of those, and 1 A564. The IC's are 1 1458, 2 4558's, a 4013, but the delay is 2 MN3004's instead of 1 SAD1024. (I think it's 2x512 vs 1x1024 stage device.)
    Been a long time, but I seem to think it was called a Bucket Brigade chip.

    I'm thinking the MXR and Univox circuits may work very similarly.
    Time to investigate.

    Hello,

    I think you should be looking for a 2SC536, the 2S is most times not printed on the transistor.
    The other one is most likely an 2SA564.

    Yes, thanks. I thought so too.
