IC´s are CA 3094 .... as written. The same like in the small-stone phasers.
The only sad thing:
No picture from the solder/track side....

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

Sorry, didnt have time to take it apart to do the solder side yet. Some of these old pedals also have become fragile and if it looks like it may break then I wont take it fully apart. I will look at this one later.
It's easy enough to guess the circuit close enough from the top side.
The CA3094 is a CA3080 OTA plus a darlington transistor buffer in one package. It's essentially half of an LM13700 or CA3280. The OTAs are almost certainly in the same OTA phaser circuits as the ca3094 version of the Small Stone.
From the colors of the auxillary parts, six of them are phase stages (all identical) and two are used in a Small-Stone-like LFO. The transistors probably do the input buffering, output mix/buffer, and maybe an active power filter stage. That is, it's a Small Stone with two more phase stages, a three-notch instead of a two-notch.

IS THERE CHANCE FOR TRACE SIDE?

Back in the 70's I had one of these. The pedal altered the speed of phasing (which seemed like a waste of a pedal to me). It was a very similar circuit to the Small Stone (it might have been a copy, but with extra phase stages). This thing hissed so much it sounded like you were playing under a waterfall!!! It was stolen at a gig and really wasn't missed.modman wrote:https://www.diystompboxes.com/smfforum/ ... ic=43677.0

I replaced it with a homebrew 8-stage phaser with three preset sounds selectable with three footswitches. The replacement served me well until I gave it to my nephew last year.
