NOTICE: Be sure to enter the Make & Model of component you are purchasing tubes for. Failure to do so will delay processing of your order. We do not ship tubes without this information.
Please Note: These tubes come factory matched, but we still test them ourselves on the Amplitrex AT1000 tube tester to make sure you are getting the best match possible. The price above is for a matched pair of tubes! If you put "Quantity: 2" you are ordering four tubes in total!
The new Shuguang 845B is an amzing tube, but don't take my word for it... let's see what Roger Gordon of Positive Feedback Online has to say about the differences between the stock Shuguang 845, and the 845B:
"To summarize, the advantages of the Shuguang 845B tubes over the standard Shuguang 845 included less noise, better handling of low frequencies, a smoother, more natural sound, and greater detail... It is like going from a $1500 preamp to a $4000 preamp. You can enjoy the music through both, but once you have heard the $4000 preamp it is hard to go back to the cheaper one."
