Hello,

I want to upgrade the old opamp in my phonostage. The voltage 22+/-

Ive used in my SU-V8s OPA1612 but they were 17+- V

? any thoughts

Thank you

only one i can see in the LME49860, which isnt bad for a cheap opamp.
Another cheap opamp that work @ + / -22V : OPA2604
Thank you Glennewdick and Sleepwalker65. I know of the Burson, they are expensive, but heard good things about them, space would not be an issue as its plenty of room, even put film caps in place of the 4.7uf bipolar caps? maybe

THanks Imhififan,  only one i can see in the LME49860, which isnt bad for a cheap opamp.

I second the Burson Audio discrete op-amp. While I’ve not yet tried them, in principle I love the idea. Plan to get some V6 units for my NAD PP2 which I’ve already upgraded the power supply on from a wimpy AC adaptor to a LM7824 regulated supply with 4700uF pre-reg filtering and a Schottky rectifier diodes. 

I would highly recommend you look at Burson Audio's Discrete op amp replacements. they are larger then an op-amp so you may have to look at space but they do offer some extenders to allow more flexible installation. I use a set in my MSB DAC and they are a huge improvement to my old out dated DAC.

Thank you. Yes i hope hoping i could use the OPAs but is risky given the 22v, sure it will be better than the old 4560 o[amp
