On the 1176 manual the attack time range is rated from 20 to 800 uS
By looking at the schematic from Gyraf audio if the attack potentiometer (R77) is set on the slowest setting we get 25k series resistance after the rectifier
With C27 (220nF) the RC time constant is equal to around 5.5 mS
I really can't see how C27 is getting the extra current for 800uS at slowest attack
I then simulated the side-chain circuit in spice and the fastest attack possible is also higher at around 100uS
did the calculation again for the release and it's the same as the manual
Is the attack on the manual wrong or i'm missing something?
