USD $‎11.95
The Chinese (Sino) 12AX7 tube (made by Shuguang) is popular with Marshall owners for its gain and bite. It is currently re-branded by Penta, Ruby Tubes, Groove Tubes, and many others. Regardless of the name, they are all the same.

Note:  These tubes are often not labeled or Shuguang labels them "12AX7" only, and does not include the "A" suffix.  However these are "12AX7A" tubes.

when are Shuguangs going to be available?


i can’t get Shuguang 12ax7’s due to the fire allegedly- but my JCM 900 doesn’t sound good on any other preamp tubes !!

Fabulous tube with one issue.


I love Shuguang 12AX7A preamp tubes. and more important, so does my Marshall amp. i love this powerful gain & low noise factor. The only thing i can gripe about is the 3-4 month life. surely there’s a way to correct that. all i can say is this THANKS for the tone. love it. Oh please rebuild your factory and get back in business. i have been scraping and searching for the few remaining shuguangs out there.
