Jenks, Cutting R41 doesn't actually cut the power to the opamp so it hasn't done what you hoped. The power to the op amp actually is from the 9v regulator shown on the schematic as U10C. > I have a lot more space at my disposal - should I use a film cap > instead? My guess is the Blackgate is plenty good enough (Rest of > system is pretty good - Rowland Model 201 Monos driving Verity > Parsifals, signal cabling is Jena Symphony). I think the Blackgates are very good but some of the better film and foil polypro caps are a bit better. People have nothing but good things to say about Auricaps and there are other brands that people like as well. By the way, I really like Verity speakers - your system must sound great. > My question is - have I stuffed up?

But you haven't really disabled the output opamp either so you might be getting some strange mixing of signals. At the very least I'd get rid of the op amp output caps (C44 and C45) or cut the lines going to those caps so you can guarantee that the signal from the op amp is out of the picture. ---Gary -- GaryB ------------------------------------------------------------------------ GaryB's Profile: http://forums.slimdevices.com/member.php?userid=3169 View this thread: http://forums.slimdevices.com/showthread.php?t=19822 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
