- ELectro Harmonix and Sovtek are not the same tubes. They are both owned by New Sensor, but are made in completely different factories with different specs.
- The Sovtek tubes are inexpensive, the Electro Harmonix are not. Never pay the same for the same tube.
- The Sovtek 12AX7LPS is a good 12AX7 tube for the money, you heard it here first.
- The JJ 6922 is the only non-NOS tube worth considering.
- All Chinese tubes are bad --- WRONG!! The Shuguang KT-88 derivatives, KT-98, KT-100 are great tubes. The Shuguang 6550 is a GE clone - try one of these, you Citation freaks. The Shuguang 12AX7 and EL84 are great tubes
- Some Chinese tubes are bad --- RIGHT!!! The tubes that Ming Da and Xian Sheng sometimes provide - Chinese tubes without any markings, should be changed right away.
- The Winged C 6550 is probably the best 6550 you have ever heard.
- The rumors surrounding the EH 6550 and KT88 are true - they are great tubes.
- Groove tubes has a 12AX7 that is a Mullard clone and this is the best 12AX7 you ever heard.
- The Groove Tubes 12AT7 is also great.
- Dollar for dollar, you cannot go wrong with a JJ tube
- Much ado about EI tubes. They were not that great. They are now gone. Don't pay the premium
- Valve Art tubes are the best of Shuguang tubes.
That's all folks - please send me you comments. I know that I pissed someone off here.
All the best,
Vic

I'll start off with a positive comment. The Svetlana winged C 6550 is a good tube. The first generation EI KT90 is a much better tube. Your statement about the groove tube 12AX7 Mullard copy being the best 12AX7 I ever heard is assinine. Either your experience with this family is very limited or your system is not sufficiently resolving to hear the
differences. I guess you make these one sentence pronouncements to provoke and encourage discussion. We would all be better served if you put a little more effort into explaining and defending (describing sonic characterizations of the tube) your utterances.
