Looking for Schematic for Roland AP-7 Jet Phaser

[DarkSide]

it does now.. sorry about that.




I have another version of the circuit with voltages and wave forms at various test points, but I don't want to publish that one until i can verify the voltages and wave forms with an original ap7.

DS,
i can't get it either.....

the link/jpg doesn't show up in your message.
all i get is a small little icon.....

Here's a pcb I re-drew for it.... http://aronnelson.com/gallery/3dm/r7

THANKS, Rod!

Here's a cool mod to try... Wire a jack in to by pass the trimmer and use an expression pedal. The trimmer has a major effect on the dynamics of the pedal so you'd get a wild variation of sweep using an expression pedal in place of it.

Do you have a parts layout to go with this?

thanks!

[Bill Bergman]

Yes, I hve it in a PowerPoint file.

Anyway an average Joe... one such as myself, could get a copy?

Thanks!

[Bill Bergman]

Sure, P.M. me your e-mail address and I'll send it to you.

PM sent, Thanks!

Note that the subcircuit just  before the "Jet Level" control is your good old-fashioned Big Muff Pi tone control.  Or rather, I should say Little Big Muff.  Like the Little Big Muff, this pedal simply selects from one side or the other of what would have been the rotation of a 100k tone pot.  Feel free to replace the switch and 100k fixed resistor with a 100k linear pot for finer adjustment of the "Jet" tone.  The two outside lugs of the pot go to where the 100k fixed resistor would have been soldered, and the wiper goes to the input of the Jet Level pot.

Hi!

Any possibility to get close-up pics for the 4 pole 6 pos switch? I have a Jet Phaser in near mint condition, but the owner before me have unfortunately turned the knob for the switch round and round until all the leads have been detached from the solderpoints... A close-up pic would help me to give life back to this beauty.

Many thanks in advance!
