Anyone have a schematic for thie op amp version?
Here it is. And no, TLV9362 is not a replacement for NE5532.
Cheers

It is just a different opamp in many respects, including a completely different technology- NE5532 is bipolar, TLV9362 is CMOS. Why on earth TI called it ”a newer version “ of the NE5532, I have no idea, it is a complete nonsense.

Purchase a Burr-Brown OPA2604 from Michael Percy Audio. It is the best option for the opamp. We performed this upgrade on dozens and dozens of these OBH-11 headphone amplifiers over 13 years with great results with plenty of positive customer feedback. Be sure to use a linear regulated 24-volt DC power supply too.
Yes, replace the input caps (C1, C101) with .33uF (330n) WIMA MKP2 polypropylene. Check Mouser for them. I would leave C2, C102 as is. My upgrade sheet listed the values just for reference, not that they needed to be replaced. Michael Percy may be out of Holco 22k but I may have some left in my stock.
Another question is my C6 and C106 are these BLUE items
I can tell if they are 22pf or 47 pf...
Does it matter here?
Are these good enough or do u think they should be changed out?
Thanks

Ready to send Mouser the order once I get these last two issues resolved
Then look for a 24vdc linear wal wort supply
