Great . I did as you suggested and things looked good. I then rigged up a mono y-splitter and hooked the signal from the single channel of computer function generator to both channels. I then measured the output on the both channels using X-Y alt and voila, the signals superimposed exactly.
.
The results for the line stage and phono stage look the same :).
Any suggestions on how to evaluate tube noise. The pre-amp is dead silent when hooked up so audible noise is not a problem. I just like to know how to do the evaluation, if possible. Is a computer function generator (I am using REW) adequate for this purpose?
