Questions about tubes and gear that glows. FAQ

Re: A quick question about pre-amp tubes....maybe a survey.

I recently swapped out the stock 12AX7s in my Jolida 202 (a 40wpc tube integrated w/EL34 power tubes) for some nos RCA 7025s. This change seemed to make everything, particularly the midrange more crisp and detailed. Acoustic guitar is downright spooky sometimes. I had already changed the stock 12AT7s to RCA ECC81s which tightened up and extended the bass.

I haven't tried anything other than the single stock 12AX7 in my Bellari VP129 phono stage.

How about sharing your experiences? I'm new to this too and I think it would be just as interesting to read early trial and error type experiences.
