Perfect for jcm 900 6l6 100 watt!
I have an older Marshall JCM900 5881/6L6 and these are recommended under the "premium package" the tube store always seems to recommend winners in their suggested packages and man were they right with these! The JCM900 is one of the most underrated amps in Marshall history. The biggest problem in my opinion is the factory tube choice used by Marshall for these. Way too much brittle high end and everyone was turned off by the JCM900. After replacing the stock tubes with these TAD 6L6GC it put that bottom end and clarity back in with the most creamy organic tone you could wish for! The only alteration I made to the premium package they recommend was substituting the EH 12ax7's with JJ ECC83S/12AX7 tubes. The EH 12AX7 tubes were a little too grainy for me compared. My JCM900 now out tones vintage Marshall JCM800 and others I have compared it against and I can't tell you how many people ask me what's under the hood. TAD 6L6GC-STR tubes are awesome!
