I had my Minimoog tuned up by a technician. He re-adjusted my modulation control wheel too sensitive. Is this something that I can easily adjust myself, or will I have to go back to another tech?

....nice forum - some answers are coming very late, but they are coming:
The mod-pot has only two wires. In full counter-Clockwise postion it should have 0 Ohms. Fully forward (full modulation) it should have 1,2 KOhm. This is a movement of 90 degrees - itīs a miracle, that this 50Kohm-Pot (audio/log) makes only 1,2 Kohms at the first 90 degrees...this is really special. So it will not work if you change it to a simple 50KOhm log Pot.
If the modulation begins too soon you can loosen the little screw of the modulation-wheel and turn the pot-axle some degrees- try out, in which direction (Sorry, i forgot it Wink). There is nothing that you can damage or make wrong - it is stone-age-elctric.
Just loose the two screws of the modulation-panel, pull out the small wood-block and remove the panel carefully. Before you kill the kabels, disconnect the 12-pole jack, so you can make your measurement very easy on your table. The jack only fits in one position - you dont have to mark it.
