Title: Swapping out the 12AX7 tubes Post by: ducblancpale on May 05, 2009, 03:22:50 PM Anyone swapped out the stock JJs for something better? Maybe Tung-Sol or Electro-Harmonix?

I swapped my V1 for a better quality JJ and the V3 for a Sovtek 12ax7 LPS there are some interesting posts on tubes in the forum. This one is realy good http://ceriatoneforum.com/index.php?topic=628.0 Title: Re: Swapping out the 12AX7 tubes Post by: ducblancpale on May 05, 2009, 05:04:01 PM I hear Tung Sol is realy good I swapped my V1 for a better quality JJ and the V3 for a Sovtek 12ax7 LPS there are some interesting posts on tubes in the forum. This one is realy good http://ceriatoneforum.com/index.php?topic=628.0 Thank you for the link....very good info. in there. Do you think there's a benefit to changing the power tubes? Title: Re: Swapping out the 12AX7 tubes Post by: Steven_nl on May 06, 2009, 07:13:58 AM For me there was.
I'm using Sovtek 5881 (just like Larry Carlton). Some people love Winged C's. You need to adjust the bias though! That fairly easy by the way. Even I could do it. Experiment!

The biasing is required when replacing output tubes only (the 6L6's). Title: Re: Swapping out the 12AX7 tubes Post by: Steven_nl on May 07, 2009, 06:59:17 AM Yeah I was refering to the power amp tubes in my last post

The Tung Sol 12AX7s are very gainy (too much for some situations, IMO). They sound pretty good, but I have had several go bad prematurely (after a few months),. Not Good. I also have a lot of experience with Sovtek, Groove Tube, EH, misc chinese 12AX7s, etc. I have some NOS Mullards, RCA Phillips, and a few others, as well. After all this experimentation, I have come to the conclusion that the JJ 12AX7s are the most consistent for good tone and reliability. I buy my tubes from Bob at Eurotubes. He hand selects his tubes for different applications and sells them that way, and I can tell you that the use of these specially picked tubes really makes a difference. Especially for the PI tube. BTW I have had Sovtek 12AX7s, EL34s, 6L6s and have been disappointed with all of them. The reviews on Sovtek 5881s are not very good either, notwithstanding the fact Larry Carlton makes them sound pretty good to my ears.

Eeverybody always raves about the Winged C's. I didn't care form them much. But I think it has a lot to do with certain batches being better then others. My tech says JJ's are pretty consitant. |
