Product Reviews
My go to 6L6 tubes. These tubes hold up well and are always quiet. They also last a long time. Nice highs, warm low mids and high mids and controlled bass response that is tight. As for new production tubes these are very well balances vs price to quality. Recommend the burned in so there’s no bias drift after several hours of use. Ymmv.
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.
