I have the upsampler(minus a few broken feet in shipping) installed.Anyway I seem to have an intermittent issue,,vocals/music will momentarily become "fuzzy" and then return to normal. I've changed tubes with a known/tested pair. I think that it is the upsampler. In order to rule it out,I need the three chips that go in place of the u/s. Does anyone know where I can get a set? Any help/direction is appreciated.
