Quad of JJ 6L6GC Power Vacuum Tube

Put these in my JCM 900, a nice step up from the Groove Tubes (in my opinion), and cheaper. Great so far, excellent tones with single coil and humbuckers.

Replaced the tubes in my amp with these and could not be happier.

After being down for a few months my twin reverb is back to life

Perfect fit

These sound amazing! Crystal clear and warm!

These tubes sound great! they do sound different from the 5881 that were in the amp prior.I have no regrets installing them

Great tubes. Fast warm up for my vintage peavy amplifier.

Pretty good shipping time considering the pandemic. Arrived in perfect condition. They work as advertised. I have so far only used one tube spot to test all 4 -one at a time. Still need to try the set together. Update - all installed, these are great tubes for my Fender Twin Reverb amp!
