  • 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. We are now using the factory direct Shuguang 12AX7B in place of the Ruby AC5HG(same tube) 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 - Shuguang 12AX7B

V4 - Shuguang 12AX7B

V5 - Shuguang 12AX7B

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!
