I found these tubes and I'm not sure what the deal is with them. Would they sound good in my amp? What type pre-amp tube are they? What tube slot ect. or are they just {censored}. Any help would be greatly appreciated. Thank!-Jeff

 

The first one is a Mullard with the markings M813? and the one on the right is a West German Amperex 12AX7A.

I think that is a military-grade Mullard, and a later, orange-globe Amperex.


Both excellent and expensive these days.

 

 

Thanks chuckgp:thu:

 

Would either one of these tubes be an improvement in my amp? If so or not, What type of tone would they provide? High/Low Gain?

Either would provide an excellent tone, IMO. I use Mullards only now in my BadCat MiniCat and X-Treme tone pedal.

 

Depends what's in your amp, and what you like. Experiment and see what they sound like.

 

Go here and check the 'Reports and Reviews' for descriptions of the different tube's sound. There's probably other sites too.
