New project added:(01 nov/2011)

DC-DC converter based bipolar power supply for effect units and portable devices.

Some circuits require a bipolar power supply. In a portable unit like an effect pedal, that can sometimes be troublesome, since it is likely that we want to power our effects with a standard 9V or 12V wall-wart or batteries and don’t like the idea of putting an AC mains transformer plus rectifiers and filtering into our boxes. That’s where a Dc-Dc converter based circuit can be an alternative:

Lately repaired:

TR-909

Another TR-909 for repair on the Bench. This is actually the 4th TR-909 I am repairing!

It came with a problem on the bass drum ‘Attack’ parameter, turning the knob wouldn’t do anything. I thought this would be an easy one and a good cleaning of the potentiometer would cure the problem but not so…
