A-128 TL064

A-128 TL064

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!

TL074 can be used. This will probably increase the current by about 50% (i.e. 30 mA instead if 20 mA). But I think you will not
notice any difference provided that the module is operated with full audio level (e.g. sawtooth output of a A-110-1).
