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.

 

Whats the transistor number, also does it use op amps like the TL072/74/84, or the NE571?

there are some diagrams here of all sorts.

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.
