I chimed in on this thread (I think?) earlier this year about the Mil-spec Raytheon 6AK5s and I just want to reiterate that they are an awesome tube! Honestly they give the Mullards and RTCs a run for their money. If anyone else wants to try 'em look for the JRP 6AK5 which denotes the military spec. Great tubes!
