Is there a addendum to the manual? > Thanks in advance > Rudy The attack time cannot be calibrated. The three ranges are realized by switching the main capacitor (100nF/2.2uF/100uF). One buys the long decay and release time (up to 5 minutes and more) by the longer attack time because the charging current of the capacitor (100uF for the high range) is limited by a serial resistor (R9/2k2). But you may reduce the value of R9 to obtain a shorter attack even in the high range. R9 is the 2k2 resistor located between the attack and decay potentiometer near the front panel. You find R9 also on the silkscreen overlay of the A-143-2 on our A-100 DIY page in the separate document "Timing capacitors of A-100 modules".
