845 Tube Refresh

Most of the info I find on new production 845 tube recommendations is a bit stale. Some of the variants recommended are no longer readily available. I just bought an 845 tube amp with basic Shuguangs and I am wanting to try something else without spending the price of the amp all over again. NOS 845s are too expensive for me to consider. What say you 845 fans?

@ test pilot. No they don’t. My bad.I was replacing my four 300 B tubes at the same time and I did  consider the Takatasuki that the Parts Connection was carrying. Thanks for your correction and sorry for the confusion. I went both 845 & 300B with the Psvane Acme Supreme series.
