This is the infamous Sylvania 6L6GC USA tube (Philips ECG). The tube picutred above is actually a 7581A which is the same tube, but has a higher military spec. and can take a higher voltage. It sounds the same, and is the same size, etc. These can still be purchased NOS for about $120 for a quad which is really quite a good deal for tubes of this quality. These tubes were used in many Fender and Mesa amps in the 70's and 80's. In particular, the original Mesa Boogie 60/100w amp (now known as the Mark I) was designed around these tubes. If you own a Mark I and don't have these, get some. I was shocked at the tone improvement when I changed them out. Amazing tone!!
