In Reply to: Are There Any Issues Using 12au7 in Place of 12ax7s? posted by jaydacus on April 1, 2016 at 16:34:08:
Further, all 12AU7s are high-distortion when used in a gain stage. (Unless a lot of NFB is used.)So you will have be listening to quite high distortion.
I recall that you used 12AT7s in place of 12AU7s in the VTA ST120, I for one am not at all surprised that you didn't like them. The circuit isn't designed for them. Of course they sounded wrong.
Why do you imagine changing tube types - as against changing brands - would be an improvement?
Do you have any understanding of audio reproduction circuits or are you just trying for effects - as in a stage/PA amplifier?
