Thanks Viridian and Drrsutliff. I am going to open up my amp tonight to take a look. I have also noted that there are a number of variations of the OPA-627 which I will reseaarch a bit more. I plan to tube roll also but I noted that in the 6 moons review of the level 2 mod of the Unico that the reviewer attributed much of the improvement in dynamic drive and frequency extention as likely due to the replacement of the op-amp to the Burr-Brown's. So I thought that if this was a plug and play operation, that I might get some appreciable improvement by doing this myself.
Op-amp replacement for Unison Unico
I would like to upgrade the op-amps in my Unison Unico to the Burr-Brown OPA627. Does anyone know if this is something I can do myself simply by unplugging the old op-amps and replacing with the new ones? Or is there more to it in which case I should leave to some who knows what they are doing.
Thanks
Thanks
