Warm tones, sweet overdrive. Same as TAD 7025-S and Preferred Series 7025. The HG+ are graded for the V1 spot. The new 12AX7AC7 is the latest tube developed at the Shuguang factory for Ruby Tubes. It is the quietest of all Ruby 12AX7 type tubes, both in terms of microphonics and mechanical noise.

Peavey 6505 MH retube Review by Dave
Hi, thanks for your recommendation on the Peavey 6505 MH tubes. I'm really happy with the change the new tubes have made in the amp's sound!

DAC Review by Robert

Your recommended Ruby Tube was better than expected. Even cold out of the box it was better than any previous tube I had in that DAC. Now, after about 15 hours it is so good I cast aside any thoughts of replacing my Mid-nineties era California Audio Labs transport and DAC. One of the best investments I've ever made.

Thank you,

Replaced Stock Fender Groove Tubes in Fender Pro Junior Review by David
I bought this to put in my V1 spot, along with a Ruby 12AX7AC7 HG for V2-
I also bought Sovtek EL84's for my power tubes.
What a GREAT combination,
My amp came back to life! The stock tubes were at least 5 years old,
they still worked, but rattled like mad and had an ugly edge to the overdrive.
These tubes, especially with the Ruby 12AX7AC7 HG+ in V1,
really gave my amp much need warmth, clean, sparkle, and gain.
I have increased clarity, better response, higher gain, more crunch,
more headroom, more warmth, and more sparkle!
Oh and last but not least, no more tube rattle!
Fast shipping and great price-
Highly recommended (Posted on 8/4/16)
Digitech 2120 retube Review by Matt
These Ruby HG+ 12ax7 tube are absolutely killer in my Digitech 2120. Nobody can believe the wall of sound metal tones that I can get out of it. Matt (Posted on 5/15/15)
Tungsten Crema Wheat retube AC7 HG+ V1 Review by Dan
For my ears, I have never played, heard (or felt) a better sounding amplifier! The tone is now huge and buttery smooth. What low end! These new tubes in the Crema Wheat are incredible, particularly the NOS 6V6’s. What a difference the right combination makes! Thanks for your help. I’ll be back!

Orange Rocker 30 retube(Ruby ac7 HG+ in V1) Review by Rick
I finally ordered the tubes you recommended for my Orange Rocker 30. What a difference! They amp just came back to life and has never sounded better. This is what an Orange is supposed to sound like! The tubes got here in Southern Oregon in three days and I could tell that extra care was taken to pack them so they would survive the trip. Thanks again, you guys rock, and now, so do I!

Genz Benz El Diablo 60-C combo Review by Jim


I installed the Ruby AC7HG+ in V1 as suggested. Impressive. Cleaned the El Diablo up nicely. Crunch and clean are both much improved. I will order the suggested V2&3 in a couple weeks.

Thanks, Jim (Posted on 7/25/13)
