Product Reviews
Again thankful that folks like JJ continue to make these tubes. Their 6L6GC is a solid performer, I have been using them for years in my customer's and my personal amps. They sound good, bias well, are pretty durable and last for years. Highly recommend!
JJ 6L6GC, I purchased the APEX matched Quad for a 100 watt Fender Super Sonic Twin I recently purchased and in the process of giving a complete overhaul. These tubes are LOUD and CLEAR in this amp, probably the loudest 100 watts I have heard in a long time. They are surprisingly smooth and clear with a clear bottom end and plenty of thick tone, they really sing! Playing a Les Paul Classic with a TV Jones Power Tron Plus pickup and the tone is awesome, from crystal clear to snarly and growling, this rocks. Thanks Antique Electric Supply for your awesome service and help. I live in Florida and the free shipping only took a few days! Cheers!
I know the product well, but my review is for the best customer service around
Thanks!
Thought I would see if 4 new JJ 6L6GC tubes in my McIntosh 240 preamp would be an improvement , actually I think it sounds better with my old tubes. Sorry!
These tunes brought new life to my Fender amplifier.
Great product, great price.
Thanks.
Excellent power tube. These are sweet sounding power tubes-and a great value. I use them in a Prima luna Prologue 4. I'm a huge EL-34 fan-love the PSvane Classic hifi el-34, the JJ El-34l-but the JJ is a great alternative if you are looking for a more powerful presentation, I bought all these tubes from AES-all Apex matched and burned in!!. Thanks, guys, for having such cool, capable and great sounding tubes!!:)
JJ power tubes good. I always get the rated wattage or more on any amp I put them in. Frequency response good. Converted an old Twin Reverb to cathode bias. Terrific sounding amp. Doesn't take much in this configuration to get asymmetric and then cutoff distortion from the power stage. Happy amp! Angry amp! Happy amp! Angry amp!
Best deal on 6L6GC tubes around. Recently installed a bias matched (Apex) quad of JJ 6L6GC tubes in a Fender Bassman 100 tube amp. The amp sounds amazing with tons of volume and full tone. Highly recommend.
Accidentally broke 1 of 2 of these tubes in a 1955 Seeburg Jukebox. Replaced them both with a matched set. I did not think the Jukebox could sound any better than it did, but it does. Very pleased with these tubes.
Awesome tubes! Well matched, great output.
