Stereo Vacuum Tubes Psvane WE205D WE205D-L Tested Western Electric 205D Replica Version
Attention:
The difference between WE205D and WE205D-L is pin, WE205D needs to match original WE-style tube socket, while WE205D-L only need flat quadrangle tube socket.
WE205D socket is as the same as original Werstern Electric 205D socket, 4 pins are the same size,
WE205D-L socket is as the same as 300B tubes, 2 thicker pins, 2 thinner pins.

205D tube type was originally developed by Western Electric in the early part of 20th century. It’s a direct heated triode tube like 300B, but with lower output and extremely accurate low voltage amplification, greatest fidelity and linearity across all frequencies in telephony. Like 300B, 205D tube wasn’t originally designed for hi-fi use. Western Electric didn’t license 205D use to any other companies, so this tube model was never widely used and hence extremely hard to find today. A pair of New-old-stock WE205D original tubes can fetch over $2000 per pair on the hi-fi market today and it’s extremely rare to come by.
Because of its extreme accuracy and great fidelity, 205D tubes have found their new amplification today in extreme high end tube pre-amplifiers.
Psvane WE205D / 205D-L Replica tubes:
The Psvane WE205D/205D-L Replica tube is developed to allow 205D amp owners to experience the full potential of 205D tube amplification, without having to spend thousands of dollars. As the original WE205D has a different tube pin size and such a socket is hard to find, Psvane replica tubes offer two tube pin options – one (WE205D Replica) is exactly like the original Western Electric 205D with 4 smaller/shorter pins; the other (WE205D-L Replica) has longer pins like a 300B tubes and it can be used with a standard 300B type of tube socket (2 thicker pins, 2 thinner pins).
Because the Psvane WE101D replica tubes also adopt Western Electric’s open plate design, the production process has to overcome many difficulties and production quantity is very limited.
