To me the best all around 5751 is the GE 3 mica Black plate...Other 5751's are also great, but found the GE to have the best balance all around...

  • To whom more was given more will be required.
    • Never go to a psychiatrist, adopt a straycat or dog. On the street they live only two years average.

Can't go wrong with any of the tubes already mentioned.  Let's not forget the RCA black plates as well.  I just rolled in the GE 3 mica black plates a few days ago and yes it has more oomph than others but I found them to be a bit less refined than the RCA in the upper mids.

I used to like the Jan/Sylvania white box on my Conrad Johnson.

bebop,

Jud is retired and not likely to reply.

Without commenting on a specific brand, I was a beta tester for Joule in the early years and we discovered the 5751s with asymmetrical plate -- 2 punches one side and 1 on the other -- sounded best overall.
