Only thing I haven't done, but would like to, is replace the big black smoothing cap with something more fitting the Mutara's.
I will be interested to hear what you select to replace the smoothing cap Gary. I guess its the next logical thing for me to try although I must say, I wonder how much better my Standac can sound.
