I have my A-128 apart right now, presently wiring into terminals for single outputs. Have noticed that these are TL064, could I try something cleaner like 074 or 084? Was the TL064 chosen for current consumption? Would I have to multiply the current consumption for each chip I add? Perhaps this would be more appropriate on the 350-1600 & 2200-11k boards. Thanks!
