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 Shuguang 845C tube is a great upgrade for any 845-based amp. Beautiful air and detail in the highs that is never bright, smooth mids, tight bass. Incredible imaging.
Please note that the Shuguang 845C tube is a metal plate design and has a 70W maximum plate dissipation. This is significantly lower than the typical 100W expected from traditional graphite plate 845 tubes. This must be taken into consideration when rebiasing your amplifier, so please contact your amp's manufacturer for proper guidance! Upscale Audio is not responsible for damage caused to your amp if you bias these tubes too hot (plus you will void your warranty on the tubes)!
