  • NOS Bejing 12AX7


This is a the "6 12AX7" version of the Doug's Tubes preamp tube cocktail kit and we've received great feedback on it. The tonekit allows hi-fi and guitarists alike to experiment and "tube-roll" preamp tubes in different slots of their amp. Substitute the V2 JJ with the NOS Chinese(foil getter) 12AX7 from Beijing for a some amazing tone. Currently we're recommending the following:

V1 - Tung-Sol 12AX7

V2 - JJ ECC83

V3 - Ruby 7025SS or AC5 HG

V4 - Ruby 7025SS or AC5 HG

V5 - Ruby 7025SS or AC5 HG

V6 - Sovtek 12AX7 LPS

Mesa Boogie Dual Rectifier Roadster full retube Review by Cameron
Played the amp last night for several hours after changing the tubes. I just wanted to thank you for putting together a great tube swap for a great amplifier. My Mesa Roadster sounds fantastic! It is very quite and has a very pure tone. I was able to really dial back on the gain and get some amazing tones with less noise. I'll be honest, I was a little hesitant to order non-Mesa tubes, but I'm glad I did! The reviews on forums and on your website can be believed and I'll order from you in the future. Thanks!
