Valve Art is a Chinese company, isn't it? Do you know who we could talk to about this? It would be nice to hear what the manufacturer has to say about it.P.S. Seeker - Sorry to go on and on about Valve Art's 2A3. That's just exactly what you said happened at the other place. But the problem with the Valve Art 2A3 is exactly why I'm interested in the Electro-Harmonix 2A3 tube you mentioned when kicking off this thread.
