New to this forum and have enjoyed reading posts from y'all for quite awhile. I appreciate the seriousness you seem to have for purest audio sound and doing it yourself especially. I have a Ward Beck console that came from a TV station and I finally decided to overhaul the rest of the caps and replace the op-amps. Done power caps and cleaned the faders but have always stayed away from the audio path caps. They are all tantalums. Now I need to redo them. I figure after being on for over twenty years they could use a little help.
I want to have some channels all electrolytics of different brands and then leave a few channels tantalums. I thought it might be cool with slightly different sounding pre's. I have two sets of master modules so I felt I would do a set tantalum and then a set with electrolytics. I was wondering if someone could check out the schematics and give me idea's on what caps should be replaced with larger values and some good op-amp replacements. I have tried OPA604's and got a little oscillation, when the pan switch was engaged. I have had some Linear Technologies recommended by a tech, models LT1122 and LT1037. The op-amps needing replacement are LF356n and LM301an. You can look at the schematics at http://photobucket.com/albums/v215/cserig/
Thank you so much,
Chris
