I need help identify big black diode. Big shape with torpedo shape. Is written 2A 1200.

thanks!

no. only had chance to peak inside. I could not trace myself as everthing to tight.

As there are no LDR/LED combination in this, I guess it work by the principle to use JFET as a variabel resistor. Similiar to following link, but using fets as buffers/amplifiers instead of opamps http://sound.westhost.com/project49.htm TL061 and BC550 probably part of LFO. interesting points - use ...

not sure if the bearfoot version has been discussed yet

Happy New Year!
