Todd and anyone else who's talking about changing chips -- do you have any idea what the w-mod and/or p-mod involve?
I don't think anyone knows, since I don't think Doug Oade has made this info public, and I think he sands off the part numbers on his mods, does on the SBM1 mod anyway since I just had a chance to crack Tim's open.
Doug has said in a general discussion of op amps that if you like the Apogee sound, the National Semiconductor LM6172 is a good one to use and if you like the Grace sound you might try the Analog Devices AD712.

Is anyone fiddling with the B-B OPA 2132U chips ?(Buy American
)
Was up on DATHeads a while ago.
I've got a list of likely subs for Op-Amps on the UA-5, and am working up a proto board. If anyone wants to compare notes, e-mail me.
I'm no Doug Oade, but he won't touch my UA-5 that was an ebay purchase that I did digimodified..........
