Some of us are well aware of the many projects Craig created for his book and a PAIA made unit had come across my bench for repairs (was sold in kit form and had cold solders galore, was a miracle it ever worked right.) but anyway I remember the tracking being nice and there’s a mod to make it...

I would very much like to have a PCB available for this too. Maybe a spot for a DIP switch for phase reversal?

Would be a cool idea I think.

Would you be willing to sell me the proto board?

https://pdfslide.net/documents/rockman-x100-and-soloist-schematics.html Here is the schematic. Doesn’t seem to wild under the hood, I think Smallbear sells the MN3007 and the Bellings equivalents.

Would be an interesting project. Originals are getting pretty expensive.

Someone is sending me a board that used 2N5754’s for the phase stages. I’ll have to see if it was changed up to accommodate them or not.

One thing I guess you could add is maybe a switch to lift the 3k resistor out of the circuit (the one that feeds into the drain of Q8 in the official schematic) to achieve a vibrato effect.

I am quite shocked that I couldn’t find one here let alone anywhere else. Used 2N4303’s for the phase stages IIRC, the 2N4303 is an oddball but apparently Smallbear sells something that will work as a substitute. Maybe something more readily available could work as a substitute like a 2N5754...
