Jul 5, 2006 · Hi All, Please advise what would be the best bet for a modern replacement of the NJM353 in my 12-15 years old vintage 4X60W Class A Zero Feedback car amplifier? Tried dual OPA627AU on adaptor but the sound is of reduced volume, of loss details and PCB is warmer than before and the noob in me did not realized the input current of 7mA X 2 or 14mA for the each of 4 dual adaptor as compared to Jun 23, 2007 · Currently it is working with NE5532. That seemed like a reasonable target for the supply current of the OPA1656 as well. I have also used a lot of different OPA types and like them a lot, but as I said, in this case I am going with what I have on hand and these 2 are proven decent stable parts.

The OPA1611 (single) and OPA1612 (dual) bipolar-input operational amplifiers achieve very low 1. Sonically they’ve very nicely balanced but lack dynamics. Different opamps have differing decoupling requirements too, so that might need checking. This changed completely when I plugged the v5i in the B4.
