Yes, it is an E55L.  I wonder how stable it is.  Interesting to me how many of these "uber-tubes" are designed for RF operation.  Should make a wonderful oscillator.  The other find I came across was a pair of 6CL6.  Makes me...

Jim, Isn’t it the same as the famous European E55L? If so then it is a very popular in certain circles tube and it is a good driver. I never tried it myself though and I can not comment about it sonic signature or how to use it. BTW, the way how you ...

Hello first, as I am new on this site... I have tried a number of high Gm pentode/triode tubes, including E55L and, of course, 7788. All are very linear when used as triodes, but do not bet on very low noise, if that is what you would be after. Th...
