It's A State of Mind

New tube, Well kind of.

This afternoon I received and installed a “new” tube into my Presonus Studio Channel Tube Preamplifier.


As you may know a lot of tube gear comes from the factory with a shiny new Chinese tube and for those looking to upgrade their gear and their sound replacing the tube with a vintage tube is a great way to go.  For this I took to eBay and purchased myself a 1960’s Tung-Sol 12AX7 tube.  So while it is new to me and it tests as New Old Stock, it is not actually new.

Now that I have a serious upgrade at the tube the real question is, How does it sound?  Well honestly I don’t know yet.  I just installed it and snapped a couple of pictures.  I need talented artists to get into the studio and try it out.  And then you will now.

  1. How hard was it to install a new tube? I’ve been considering replacing tubes in my gear with something else to get a different sound, but I’m worried about messing it up…

    • For the Presonus Studio Channel it was incredibly easy. Take out about 6 screws to open the top of the case. Then hold the mount with one hand and gently pull the tube out. May have to wiggle it back and forth a little bit. But it’s a 5 minute job. I’ve looked at changing out the tubes in some of my other gear too, some have tube shields that may require a couple more screws out. Just make sure to get the correct sized tube for replacement.
