If you can bias the amp yourself, you have more options, but if not, it's best to stick to what you know works. I am very happy with the Shuguang 845Bs in my Viva. A definite step up from the stock Shuguang 845s, which are not bad IMO. I just think the Bs have a bit more tonal color.
845 tubes. New not old stock
My Triode Corp of Japan 845 amp will need new power tubes within the next year or so and I am curious which 845 tubes are being by used by others and how much they are liked. I currently have Psvane 845T, which sound good. These are the original version. I tried out a pair of Dragons which were not as lively as the Psvane 845T's. I am considering Psvane 845 Tii or the KR 845's. Are there any other new manufacturers making 845 tubes within the last 5 years? Unfortunately all of the NOS 845 tubes are out of my price range ($7500!). I would like to keep it under $800/matched pair.
Thanks all
