OK, Aharon: you want to figure out the offboard-wiring ?
Have a look here, but: caution that you don´t get nuts, from the highres guts:

Could you smell the vintage electronic ?

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.
Wow! how things travel on the net... That looks suspiciously like the copy of the AP7 schematic I scanned! Cool...

Just wondering if someone have the schematic of this pedal. Thanks

Can someone tell me why this unit sounds so good on bass? I've tried (too much) phasers on bass but this was the only one that stood up my abuse / thoughts on how one should sound on bass.
Great unit btw!

I was looking into this subject now for a long time; need to build one for my bass use (as does Larry Graham)
There are 4 JET settings, 2 non jet setting and a fast / slow setting on which only the slow speed can be set by a potmeter
1 and 3 JET give shallow modulation (depth is determined by point 10 / 12)
2 and 4 JET give a deep modulation
Difference between 1-2 and 3-4 are the JET EQ; one has mids, one lacks it.
5 and 6 are just shallow and deep modulation without the JET
You can make these changes more easily switchable with individual switches.

Or are they uploaded elsewhere?

Ok, here you go for the track side..... and as a "bonus track" you will get the component side too, taken by ebay user "coastal.a.a".

Let me know if you manage to work this out.
Again, this is downloaded from somewhere which i couldn't recall now. If anyone know where is the origin, give him a credit.

Hey....
What size do I need to alter this too, so it doesn't print out a full page sized pcb? I hope to get this etched today.

Okay i printed this out but it came out all fuzzy..I forgot its at 72dpi resolution...TERRIBLE.
So I resized the image to 5.5inches..letf the constrain portions on, 5.5 inches mind you. ANd set resolution to 1200 dpi.
I think I did the resolution first though. Did a little cleaning up with levels (photoshop again)
now I think it should print nice and clear. Still at 1200 dpi though normal 8.5x11 is 300 dpi. So just a little more adjusting and we have ourselves a rpintable pcb of the jetphase.
Now there IS a second board but I think thats for the speed control, and just a few components I can do on a breadboard, or vero or whatever.
next step is to be able to print 2 on a sheet of photopaper..or some cheap glossy paper that will still dosolve in water. I want to try to find a mixture of something that will help disolve the paper but leave the toner....

Hi...chicago_mike....i was a noob at the resolution thingy.
Appreciated if you have some guide or any link to share to get thru that, especially how to play with PHOTOSHOP for RESOLUTION and SIZE.
TQ
