YAPS1A Mini

[juansolo]

A 2nd Maestro PS1a clone in a small box. Again it runs our tweaks to make it play nice with guitar (detailed on the main site).

It might look a bit messy inside but it's all keeping the signal away from everything else. The last one we built we ended up having to shield everything. This one we've got the same result through a bit more sensible routing of wires and jacks (ie, nowhere near the LFO!).

Still a tight fit, and still a bitch to build, but a bloody marvellous phaser.



PS1a board from Alan P. We've just bypassed the AC supply with our own DC supply.

Beautiful like always! Is that a commercial board?

This is still on my "must build" list. Looks great man.

It's a board I laid out awhile ago -- Rej has a better one under development.

Mine has an onboard linear PSU that takes 12V AC in, and puts out +/- 12V DC. Juan prefers to use his 9V DC -> 5V -> +/- 12V PSU, that's all Linear PSU means no charge pump clock to contend with.

I'm not happy unless I can run everything from my standard 9v DC PSU
