Hi Ken I'm calibrating some CGS48 VCO's and i need to know what position to have the knobs in to adjust the ZERO trimmer. I have the 'Tune' knob at 12 o'clock. Does the position of the 'Frequency' Knob have any bearing on the calibration process ? Should it be at 12 o'clock too ?

Seriously, I doubt your ear would pick up the difference, assuming there was any difference. I've not gone over the design with distortion analysers etc, so I can't give a definitive yes/no answer. Ken >Would Styrenes be an improvement sonically in the 10n , 22n and 47n positions

Hi Ken I just wanted to ask about Styrenes in the CGS202. I have used Styrenes for the 220pF (x 4) , 680pF (x 2) , 1nF (x2) , 2n2 (x 2) and 4n7 (x 4). As visible in the picture on the build page. http://www.cgs.synth.net/modules/cgs202_reseq.html Would Styrenes be an improvement

Hi, oh no, it's me again. ;) I have a question about the 'ASM-1 mod' that is mentioned for +/- 15 V operation: First the mentioned 330K resistor seems to have gotten a 220K in V1.0. According to the ASM-1 schematic the 240K would be replaced by a 560K and the now 220K by 200K. Bu

Oop, speaking of errors, the 2.2K resistor in the schematic of the Peak section of the Peak and Trough circuit, the one between the base of the lower PNP and the input diodes, should be a 220K according to the PCB overlay and the original Serge schematic. http://www.cgs.synth.net

It's drawing too much current for the 10R resistor. Try putting in two 10R in parallel. That will halve the resistance and double the wattage. I don't have a current figure for what it draws under usual circumstances, so I don't know if it is drawing excessive current or not. Ken

Try putting 10 ohm resistors in the power rails, and increase the value of the on board electros. See what I did for the power input on the CGS21 super psycho. Also try putting 100n directly across pins 8 and 1 of the 311, if it doesn't already something there. Also check that yo
