Metal -

Our "metal" amp tube kit is designed to produce richer, thicker, and darker tones.   It includes a "high gain" preamp tone kit, and available 2 x Electro Harmonix 5U4GB's.  The Ruby/JJ 6L6GC-CZ's give you articulate distortion and the attack response needed in metal.  Electro-Harmonix 5U4GB's are one of our best, most sturdiest rectifiers.  Our preamp tone kit is all high gain, designed so you can push your amp and is as followed:

V1 - Mullard CV4004 (High Gain)

V2 - JJ ECC83(high gain) (High Gain)

V3 - Ruby 12AX7AC5 HG (High Gain)

V4 - Ruby 12AX7AC5 HG (High Gain)

V5 - Mullard 12AX7 reissue (High Gain)



Rock / Hard Rock -

Our "rock" amp tube kit is designed to produce richer, smooth, fuller bodied tones.  .
We recommend the Mullard CV4004 in V1 - it will give the clean channel a three dimensional sound.  Placing the Ruby/Shuguang 12AX7AC5 HG in V3 and V4 will give your modern vintage gain channels a little more character.  Our preamp tone kit will give you the flexability needed in rock, and is as followed:

V1 - Mullard CV4004

V2 - EH 70025 

V3 - Ruby 12AX7AC5 HG

V4 - Ruby 12AX7AC5 HG

V5 - Mullard 12AX7 reissue

Dual Rectifier Roadster retube Review by Mike
Hi Doug, I was surprised to receive the package last night, much faster than I expected. Put those babies in today and WOW... that tube selection has really worked some magic on my amp. It sounds incredible. I finally have the tone I’ve been looking for for years. It’s tight, punchy, and chimey.

I honestly wasn’t certain about where to put the NOS Beijing, and ended up putting that in my V6. Seems to have been a good choice.

Even the FX loop sounds crystal clear like never before. All of my time based FX pedals sound way creamier and have better definition.

Very satisfied. Thank you sir,

Mike G

Dual Recto retube Review by Alex
Got my tubes in yesterday and just installed them at our practice. Holy shit dude, these make my rig sound like an absolute beast. Thank you so much for the recommendation and putting up with all my questions. My stuff has never sounded this good, I'm literally blown away at how the room shook with all the overdrive. I can't wait to play out with these! Seriously, thank you so much (Posted on 10/6/19)
Tube kit Review by Jordan
I have a Mesa dual rectifier roadster and retubed the amp with Doug’s kit for metal tones and I must say I’m blown away I had all orginial tubes from Mesa and this kit blows them out of the water I was amazed how the full potential of this amps gain was released and just how much it cleared up the highest gain channel it’s so nice to hear every note so clearly I opted for the NOS tube upgrade and it was well worth it! The clean channel I never had an issue with and it’s still just as clear maybe a little more so I would highly recommend this kit to anyone who really wants to see what their amp can do. All tubes were packaged and labeled great no guess work involved when my other amps come due for tubes I’ll be buying from Doug’s again! (Posted on 12/14/18)
EL34BSTR's Review by MATHIEU
I own a mesa dual rectifier and bought from you a complete metal retube kit with EL34BSTR. This is the best retube kit ever bought! (Posted on 3/5/17)
The Roadster is back! Review by Powers
I purchased the metal preamp kit with the V2 upgrade and stock 6L6s and am very impressed! The preamp kit really woke up the amp, gave it a bit more tightness and chime. I was a little weary because I had dialed in nice cleans on channel 1 and 2, but there was something missing on channel 4. They actually improved my cleans and did what I wanted to the high gain section. Highly recommended! Thanks Doug! (Posted on 2/3/17)
Awesome! Review by Dylan

so super sweet!! Review by shawn
I went with the metal preamp tone kit and the ruby el34bstr. Holey smokes the harmonics are amazing. also gave some life to a rather lifeless clean channel. I purchased my dual rec 3 channel used and just wasn't getting what I wanted out of it. these tubes did the job and then some. thanks a lot to dougs.. and thanks for the fast delivery as well.

Is this a new amp? Review by Jason
I ordered the metal preamp and rectifier tubes for my Mesa Boogie Dual Rectifier. I already had a set of Ruby EL34BSTR's for the power tubes. I am amazed at what it has done to channel two. With the stock tubes it was flat and lifeless. I was starting to question if this amp was worth my investment. Now channel two has as much crunch and definition as channel three but with more midrange drive. Mesa Boogie should take note and maybe start offering these tubes as a stock option. The clarity of single notes and complex harmonic structures of full chords ring out on all three channels.
Thanks for doing the homework Doug's Tubes. I'll be sending people your way. (Posted on 1/3/16)
The Definition of Night and Day Review by Robert
Doug's seems to know the capabilities of each tube and how they shape the sound based on placement in the Dual Rectifier. I would have never been able to come up with the hybrid assortment of tubes that they provided and, even if I did, would not have know the correct order of placement to get the desired results. I purchased the metal tube kit after being disappointed with the overdriven sounds of my Mesa for about 2 years. I was able to find some heavier overdrive by placing a tube creamer in front of my signal, but that always seemed like cheating to me, especially since Mesa's are known for having face-melting overdrive. After installing the Metal Tube Kit from Doug's, it's as if I have purchased a completely different amplifier... one that plays and sounds the way I expected it to after all this time. I am very grateful to Doug's as their tube kit has allowed me to fall in love with my amp all over again. (Posted on 6/3/15)
Takin' the Roadster to Tone Town Review by Demma
I was a little hesitant to stray from Mesa Boogie brand tubes for my Roadster. I decided to take a risk and go with Doug's recommended pre-amp kit, rectifier and power tubes. His suggestions addressed all my problems and concerns. I received top notch service and support. I saved some cash in the process. My Roadster sounds great. Highly recommended. (Posted on 2/25/14)
