Mike.......I have no experience with the Psvane 12AX7 tube, although I have had experience with other "Made In China" 12AX7 tubes made in the factory where the Psvane's were made. They were McIntosh branded tubes that came with my C2300 preamp. I can't speak of their reliability because they did not please my ear and were replace in short order with Gold Lion gold pin 12AX7's. The McIntosh "Made In China" tubes have been stored and gathering dust for years. McIntosh finally came to their senses and now uses McIntosh branded tubes made at the JJ Tubes factory in Russia.

I have not heard whether the small low voltage Psvane tube have the same reliability issues as the Psvane power tubes. I have read many comments about the Psvane power tubes not delivering longevity, with many early failures. I will not purchase Chinese tubes no matter how fancy the logo or box they arrive in, but I recognize not everyone shares the same few.

I spent some time this afternoon to Photoshop the Psvane 12AX7 just for Charles. Considering he has yet to discover a vacuum tube the encompasses precisely what he seeks, I thought a 12AX7 with a built in tone control would be right up his alley. Guess not.
