[/qu ote]Hi Phil, I breadboarded up the oscillator Rod Elliot's IC based tremolo circuit (http://sound.whsites.net/project29.htm) which works really well. So as an adjunct to making these LDR/LED units, which LDR did you use? Both Altronics and Jaycar carry the same 2 versions of these CdS cellsOne is a ORP-12 equivalent: Dark 10m to Light 48k - 140k, while the other one is: Dark 500k to Light 2k8 - 8k4,I think the ORP-12 was what was used in the old Goldentones and the EA Playmasters 116/117 tremolo circuitsGavan
