Mike, I'm not sure what vintage Mullard tubes you have... but the tonal difference from what I've heard between the Mullard and any 6CA7 is day-&-night. The 6CA7 gives the amp more of a 6L6GC sound and response, IMHO. Not the warm vocal midrange of a good EL34. 6CA7 = cleaner highs, tighter bass. Midrange a bit scooped out. A more sterile, less harmonic-rich tone. 3D imaging is a better with the 6CA7, IMO.

As 6CA7 go, the EH is a fine tube. I personally like the GE 6CA7. And still have quite a stash, thanks to UncleStu (RIP)... these are what I've been putting into Marshall head units. But, I have to warn ppl that they change the tone over Mullard or Tesla, which were in the amps. Tone knob tweaking usually helps. Or sometimes, I'll change coupling caps in the tone stack.

The EH last. They are as tough as the old US made tubes. Even in combo amps, which are being beaten to death by would-be axe heroes.
