  • JJ ECC803S


The JJ ECC803S are longer plated 12AX7's, with a spiral filament that reduces noise. Thick tone, these are quite popular with many of our customers. Nice in the phase inverter spot.

Customer Reviews

graet headroom tube Review by Randy
I have used JJ ECC803S for years in V1 and V2 mainly because of the clarity and the ability to stay clean at high volume due to the long plate I use these in my fender Princeton reverb reissue. They have a wonderful clarity and a fat quality and warmth that I demand out of this fender amp. Thanks Doug. (Posted on 3/1/15)
Wonderful Review by NYC LP Player
I tried these and Tung Sol regualr and low gain and these were my favorites. Gave my drive channel a Bonamassa-esq smoothness that I really loved with warmth and roundness on the high and low end. The Tung Sol regulars would be my pick if I did higher gain stuff (hard rock, metal) and these for blues and classic rock. (Posted on 11/27/13)
Orange Rocker 30 retube(JJ ECC803S V3/PI) 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!

Perfect in my GK Fusion 550 Review by Evan
I grabbed several different tubes to try out in my GK Fusion 550 bass amp. The JJ803S adds a thickness that's perfect for playing near the bridge on my G&L ASAT. This setup sounds a bit thin with most other tubes, but this one gives a great, extra fat low end and really brings out the low mid growl.

It's definitely over-the-top and exaggerated, but that just happens to be exactly what I need. (Posted on 5/18/13)
