The JJ Electronic 7027A offers the same reliability and tone as the JJ 6L6GC but with the correct pinout for vintage amplifiers that use 7027 tubes like older Ampegs. 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 7027A is a great option guitar amplifiers and Hi-Fi stereo equipment.

I will say these can handle 7027 voltages, but they don't quite cut it as a 7027A. I find it hard to believe JJ can make a 14 watt 6V6GTA, and then fail so miserably with a 7027A. If your amp takes 7027As and is running them at high voltages, consider finding NOS tubes or dialing back the B+ with a MOSFET regulator. If JJ would call this a 7027 I'd give it a better rating. These are like all the larger JJ Pentodes. If you crack one open with a hammer they all share the same cathode assembly.
