Vacuum Tube - 6L6GC, JJ Electronics
The JJ Electronic 6L6GC is the classic pentode built with the rugged construction that only JJ could deliver. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 6L6GC is a great option for guitar amplifiers and Hi-Fi stereo equipment.
Matched versions of this tube use Apex Matching

Product Reviews
Replaced old tubes in a Valveking50 w these. Sounds great!
These tubes sound incredible in my 65 bandmaster,highly recommend the matched burn in they always fire up.I have JJs in all my Amps ,65 BM 62 deluxe And JTM 45 and they are great for Classic rock and blues,The only tubes that aren’t JJ are the PI which I use the Sovetek LPS
the tubes arrived faster than expected and were undamaged. What more could someone ask for? Maybe some mints or nuts included in the box. Yeah, I like mints, but I've digressed.
Great tubes. I use JJ’s in my fender super sonic 22 (6v6) and jj tubes in my hot rod deluxe (6l6). Highly recommend. Shipping is also done professionally, tubes arrive fast through usps and are packed to ensure they arrive in working order. Thankyou Amplified parts !
Always happy with JJ Electronics products. My order is always received before expected.
Thank you Amplified Parts. You are the best deal on vacuum tubes. Tubes worked as they should.
If you are looking for a good tube at a good price you have just found it! Good Sound at a good price. Everyone's hearing is different. So, We could get a lot of argument on this subject. I have found JJ tubes to be a very good buy for the money and have had no complaints from my customers that have gotten them from me. Don't forget: If you have had a sudden output tube failure always have the screen grid resistors checked! If they are bad - when you put your new tubes in the amp it will immediately burn them up! * Not worth the risk is it?
Nice tubes. Full in the midrange with a smooth, detailed high end response. Durability TBD.
Best tubes. I re-tubed my EVH 5150 and I love how it sounds, more focused, tight, and alive.
Amp had an intermittent solder joint at one of the 6L6GC screen resistors that eventually blew out one of the original Ruby output tubes. After finding and correcting the problem a matched pair of JJ 6L6GC tubes from Amplified Parts brought the amp back to life and is now better than new, sounding great with full bottom and top end. Thing here is that the tubes I received were matched perfectly when measured on a transconductance tube tester and when biased were within less than a milliamp of each other. Signal testing with an oscilloscope showed a very symmetrical both clean and overdriven output waveform, confirming the well matched tubes. This was my first purchase from Amplified Parts and will absolutely purchase again from Amplified Parts when tube matching is needed for any of my amps since the quality and cost amounted to a very good value. BTW this is an honest voluntary review and I have no affiliation with Amplified Parts. Again, very happy with purchase.
