Western Electric 12AX7 coming this summer.

I think the big market for 12AX7 is guitar amplifiers. A lot more of them than audiophiles. I'm think this influenced WE's business plan.

I wonder how many high-end NOS 12AX7 tubes are still out there.  When those dry up these guys will have the market cornered if they can produce a quality replica.

Psvane is marketing to audiophiles and musicians.
