Best 845 tube out there?

I am running a pair of Cary CAD-211AE monoblocks with the standard no-name Chinese tubes shipped by Cary. Whilst I am happy with the sound, I think I should buy a pair of 845's to keep as backup in case something happens to these tubes.

Because I will need to buy FOUR of them, this rules out any tube that sells for stupid money (e.g. vintage RCA 845 tubes).

The only current production 845's I am aware of are:

- Shuguang 845 "standard"
- Shuguang 845B
- Shuguang 845C
- Shuguang PSVANE 845
- KR Audio 845

I have found reviews of the Shuguang 845B and 845C, but there is virtually no information out there on the new Shuguang "psvane" 845. Has anybody heard this valve, and is it a noticable improvement over the 845B and C? Also, what do people think of the KR?

I have yet to try these (845T) but can confirm that the various SuperTNT versions are excellent and worth seeking out. I have a pair of their last high-dissipation 845 metal plates, and they are about as good as modern production gets. Hopefully they will arise once again and make 845s like they used to.

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?
