Hi,
I would like to improve the IC that it's on the Mid Frequency EQ of an Alice 828 (first version with Belclere transformer and Discrete Mic Pre).
It has been discussed a lot on the possible replacements for the LM741 being the normal candidates:
TL071CP (low noise version of the TL071, pin compatible, low current draw)
NE5534AN by Signetics (not pin compatible, might need compensation caps, more current draw)
Burr Brown OPA 134A (pin compatible with 741)
I know that depending on the circuit usage of the 741 sometime it's indifferent to upgrade it.
Not understanding the circuit very well I would like to ask if in this particular circuit upgrading the LM741 would be justified?
And if you advise on the TL071CP or OPA 134A for the upgrade?
Thank you
here is the schematic:
