Mark IV preamp tubes options

[amphead]

I have these options: Shuguang 12AX7B, Sovtek 12AX7WA, JJ electronics ECC803 or Shuguang 7025. Which one to choose? Any recommendations? I would choose Sovtek's. Thanks.

Choose them all (and then some - start a collection) - and then start tube rolling.

Once you hit upon a combination that works for you (if ever); you are golden.

No one here can tell you what will ultimately please YOU the most. Just read their suggestions and come to your own conclusions.

Lots and lots of thread on this board concerning pre-amp tube selection - try searching.

Have fun with it.

Good luck.
