JJ TUBES have long been a familiar, reliable, and affordable producer of great tubes for many years, and we commend & appreciate them as always for their ongoing contribution to the tube world. TUBE AMP DOCTOR brand tubes are German engineered, tested and selected in their facility in Germany. The tubes are physically produced in their German-built factory in China. We have tube rolled Tube Amp Doctor tubes and found they are excellent. Their 12ax7 was compared to a large variety of new production & USA NOS tubes, and sounded better than most all of them, including a NOS Telefunken. Just our personal experience, thought we should pass along in light of recent events. Tesla/JJ 6L6-GC These handle voltages often used in amps using 7027A. Drop-in replacement for Ampeg, McIntosh and other amps using 7027. Replaces all 6L6-GC & 7581. Also nice sub for British KT66 in Heath W5 and others. In many amps will put out more power..up to 10% or more..than ordinary 6L6! Tesla/JJ 7027A - Not sure if your amp uses those two extra pins? With Tesla 7027A you don't need to worry. Note we recommend Tesla 6L6-GC for higher powered amps like McIntosh, ARC, Fender,and they are a direct replacement for 7027 in Ampeg "B" and "V" types ("But can I really use 6L6-GC in my Ampeg?" Sure. For more details, read the "Help, My Amp Has 7027's! FAQ") and for 7581A in Harmon Kardon Citation V. Lower powered amps,like 50's vintage Williamson type amps (Heath W3, W4), jukeboxes and most 50's guitar amps, can use any of these. |
