I've been researching AT7s for my amps driver stage and see in the archives here it's Jim McShanes favorite, BUT, one must be careful to get them tested for microphonics.
Some UK adverts for the tube cite it's construction being good for eliminating microphonics so I'm not certain what's what. I do see that NOS, sealed box CV 4024s go for around $70/pair. Not too bad.
