Okay for 6146B, but not 6146A  Time owned: more than 12 months
I have been using Shugaung Sino 6146B tubes in bass amps, transmitters, transceivers, and other stuff too, for 35+ years. Shuguang has gone through half a dozen or more variants of the 12AX7, alone, and I suspect they have made a few changes in their 6146B designs also. Their 6146B is actually a pretty decent tube, but their are still vast numbers of NOS 6146Bs out in the market, and even more used 6146B tubes made in the USA. They all tend to be better quality. If you have one of the stock transceivers like a Heathkit HW-101 buy new or used 6146 or 6146A tubes. The 6146B will not properly "normalize" in these older transmitters, (without mods) so stick with some new or used 6146As. If you have a hybrid Kenwood or Yeasu that takes the 6146B, give the Shuguang a shot. I am even using Shuguang's 211 tubes in a very old transmitter from the early 1940s. The Chinese tubes seem to have been improving in the past 5 years, and I am not the only person to have that reached consensus of opinion. I do suspect they may deliberately give these a shorter lifespan to sell more tubes. I suspect that of New Sensor, JJ, Svetlana, K&R, Krell, and EAT as well. The volume of tubes needed is not there to sustain the business without making some concessions, and keeping the prices low, and cutting quality seems to work better than charging more money. For that, I place the blame squarely with guitar amp manufacturers, and their nickel counting accountants. This lumps glass transmitting tubes into the same lot as receiving tubes. Ameritron is just as guilty as Fender, Marshall, Vox, or dozens of others in this little game. They are essentially MJF, so what does that tell you? They would rather pay less money for lower quality than demand any improvements. I have run these Shuguang tubes on curve tracers, and all manner of test gear, and they are a 6146B, but their lifespan is not as good as the older tubes made in USA, or western Europe. The Shuguang stuff today is better than ever, but it still has a ways to go yet.

Good experience  Time owned: 6 to 12 months
Purchased a pair of Shuguang 6146B tubes from local tube dealer and have been them use in my old Yaesu FT-101ZD HF-transceiver.
Tubes working as they should be.
No any kind of neutralising or other problems at all.
Get full output from 10-meters to top band.
Good price/quality!
