Best 845 tube out there?

Ed...My hope is you get some (845T) and do a proper comparision and publish a detailed write up as you have for the "B" and the "M".

I for one would be interested to read what you find out.

I received my 845Ts yesterday. First reactions are highly positive despite the fact that the innards look very much like Chinese 845As and Bs. I was using "holy grail" metal plate 845W tubes and prefer the 845Ts, but bear in mind that I've had them only one day. Dave

This is good news,Dave.
Since you've been using the 845W, your comments carry much more weight.
Give them 25-50hrs of work andI think you'll be even more impressed with them.
Look forward to further observations from you.

Hi Ed, I would second Davvie's request. Are you planning to obtain a pair of Shuguang 845T's in the near future?

I have received my Shuggy 845T's from Grant Fidelity. The first thing I noticed was that the elements on one of the valves was not aligned properly. Three of the four valves sit at 45 degrees on my amp, this particular valve sits at 30 degrees. It is not an issue with my socket, or the way I have installed it either - I removed the valve and inspected it, and it is indeed out of alignment compared to the other valves.

Whether it affects the function, I do not know. Grant Fidelity did not send me a calibration sheet (which apparently accounts for most of their premium pricing).

I have emailed them asking for an exchange for a fresh set of tubes. Waiting to hear back from them.

In the meantime, the new valves sound closed in, congested, and lacking in top and bottom frequency extension. I am not discouraged, because my "old" 845's sounded like this when they were brand new. The truth will be out once the valves are burnt in. Or rather, my new set of valves once I return this set to Grant Fidelity.
