I have an orignal Fender Blues Deville 1993. I really need to replace all tubes, i dont really understand what my options to choose from are? can someone help?

I received an ART TPS II and would like to upgrade the tubes. Any suggestions?

Hey guys, I'm relatively new to the forum. I want to get better at recording, so I'm focusing on adding gear to round out my studio. Here's what I'm working with right now-

Guys,

I know there's a few forum threads on this topic out there, but none of them quite answers my question. I want to try out a few different types of tubes to replace the standard 6922 tube inside my RODE K2. Do I need to replace this tube with the same type (i.e. 6922 aka ECC88) or can I use different types as well?

So, I'm new to tubes, but I'll be replacing the 12AX7 tubes in my Aphex 107 preamp with 12AT7's. I have read on here that they were originally supposed to be in there and the unit performs better with them.

ART MPA gold, not so great stock tubes. I've heard putting in some new ones can make a big difference, but what kind?

We might as well know this.

audio preamps, guitar and bass amps...

Who are the best tube manufacturers?
Who do we buy them from?

Why are there differences?

I can buy Behringer T1953 Tube Ultragain with changed tubes (Electo Harmonix) for 150$ is it worh it? Can u tell the diference with electro harmonix tubes? I mean yeah u prob can but will it sound better?

Well I am starting to experience great volume loss on the clean channel of my Peavey xxx. It isnn't constant however. It is also cutting out on all channels and I believe this is because of my power tubes which have never been changed in the past few years since I bought it new. I know the preamp tubes are fine as I replaced them about a year ago.

I own 2 of this units. I like them they are good gear for the price.

Does any of you recommend some specific tube brand and model that could upgrade the sound?

And now a general tube question since this is my first tube pre. Ho often do I need to replace tubes?

Thank you in advance.
