OK, my quest for perfection continues, and still at this stage I am looking for a "wow" sound....
Originally I thought there was a problem with C13 but now think its OK but my voltages for "IC12A thru D24 - R46 - C13" are:
D24 - 0v, 2.76v
R46 - 2.77v, 2.89v
C13 - 2.89v, 0v
IC12A - seems mostly along the lines of the 'analog voltages' posting/eagle file which is on another thread from quango. I can't measure mV's but the only differences are where quango reported 11.73v on a couple of pins, I am getting a bit lower - more in the region of 10.8v
i tried following some traces around these components and VR4 and noticed a few things....
R47 - getting 3.2v one side and 3.79v the other - a bit low?
C15 - 0v and 4.17v (R67 also has the 4.17 - does this feed C15 or vice versa?)
J5 - is this important? it looks like quango gave the voltages for this the wrong way round (?) but ignoring that, where he noted 34mV/0v/5.96v I am seeing 1.91v/0v/5.96v (with J5 on the I/O being the same)
C43 is also showing 2.4v on the negative side and 2.97V on the other
I am fairly positive that with enough effort I can get this thing as I want it now that i am pursuing voltages, but really would appreciate anyones help. (....and have checked that i am getting 5.3v and 11.8v)
