Those are some of the last American tubes made.They sound very good but I still prefer the black plates and the Russian 6P3Se overall..Those are very close tho and you may like them better depending on where they are used.
I realized something a few years ago. I have NEVER EVER heard a bad sounding 6L6GC or EL84,regardless of when they were made.I have heard better sounding 6L6s and EL84s than others,but I never heard one I can honestly say sounded like crap.
I think the reason for this is,they have never stopped making 6L6s and EL84s since the day the first one rolled off the assembly line so everyone is pretty good at it.

Big, clean sound. Lots of headroom. Close to the GE 7581A tone. Not quite. Not the midrange of the RCA blackplate 6L6GC. Gotta try some high testing, quiet GEC/MOV KT-66.
IMHO... no new tube has quite the headroom and big tone of good NOS. I have tried the Tungsol (Russian) reissued 7581 and 7581A and was a little disappointed. A good set of EH 6L6GC has the best headroom of any of the new 6L6GC types I've tried.

I have some Arcturus 5 pin tubes but these are Shuggie 6L6GCs made for Groove Tubes and they sound dam good.I think the coloring may have some effect on temperature and whether that changes the sound for the better I can't say. I can say that these tubes sound very good in an Mc240 MAC amp.

I had some of these a LONG time ago. Very good tubes. They has "Made In Czechoslovakia" label stamped on them.
Got the Sylvania tubes today. Test very high, mA to within 2mA of each other at 475VDC. Will try them out later this week. Hope they are as good as the 7581A I have.
