Good to hear. Thanks for sharing. The Amplitrex certainly gives you confidence in the tubes when they test high.I've tested my original Elrog 300B brass base (last of TM's takeover) on my Amplitrex 1000 and they're extraordinarily strong at over 3000 hours.
I should test my ER5U to the Mullard GZ34 but that means I need to put many more hours on the ER5U.
If you could also test the newer Elrog that would be great
