Hi Ian,
I may know a guy interested in these. I don't know much about them so I will pass on the details & see if he wants all or any of them!
Would any of them be suitable for upgrading a pc soundcard or Arcam AVR350? They are the mainstay of his system, he only spoke to me last week about up-grading op-amps.
Cheers,
Greg

PS, you still ok to meet up to sell me the Wharfedales on Thurs?
Re: FS: OPAMPS- Texas Instruments + Analog devices
If your friend can find out what opamps are originally fitted then we can go from there to find a replacement. The opa637bp are the best but I've only one left.
Re: FS: OPAMPS- Texas Instruments + Analog devices
I sent him a text to look on here Ian & let me know if there's anything of any use to him. If so, I can collect when I see you on Thurs!
Any prices btw?
