Replacement for LM318H Op AMP in BGW AMP 750 A/B

[qsa]

Hello is there replacement for LM318H possibile ?

Want improve sound in mid and high

How about LME49710 or NE 5534 as replacement

I think amplifier can better sounding with new op amp LME49710

LME49710HA about $8.30 from DK

the circuit makes a difference - the 318 was sometimes used with a discrete fet input bypassing its inupt diff pair- not many pin compatiable drop-ins for that cirucit

Keep the LM318. It's the best op amp for that circuit. There are other things you should be paying attention to, like the DC offset adjustment. Output transistor matching, in fact, try some of the newer outputs.

In feed forward, the LM318 is capable of slewing at 70 V/uS. That's faster than what you are looking at as replacements.

Use one of Linear technology's higher spec versions of the LM318/LM118 - the LT318A/LT118A.

A drop-in replacement, lower noise, better PSRR.
