One more thing: Where exactly are the cheking points for the +5 and - 5? (Assuming +15 and -14 are for the synth section only)I can only see a +5v mention next to vr1. I may be misinterpreting some symbols in the shematic and wouldn´t want to read/adjust voltages with the voltmeter connected to the wrong side of a resistor or something... All I could measure well so far were +4.8v at cpu chip´s pin 40. Thank you.
