- Psvane WE275 – equivalent to 2A3:
The 275A tube is often referred by audiophile as ‘baby 300B’ due to its silky sound. It was one of Western Electric’s early directly heated triodes and used in PP & SE circuits of the 1930′s portable high fidelity, theater sound amplifiers – like the “silver” circa 1935 Western Electric D95508 portable amp. The original WE275A tubes has heater voltage at 5V and was not widely used in home stereo.
In this new Psvane WE Replica 275 tube, Pavane Audio has modified the tube heater voltage to the standard 2.5V then you can use it to replace a typical 2A3 tube – which is of smaller glass enclosure size than 300B tube.
The workmanship and materials chosen for the Psvane WE Replica 275 tube are identical to the original Western Electric 275 tube – the design intention is to revive the WE275 legend yet still offer wide application in place of 2A3 in hi-fi home stereo.
