Chinese Psvane WE101D-L
101D 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, 101D tube wasn’t originally designed for hi-fi use. Western Electric didn’t license 101D 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 WE101D original tubes can fetch over $2000 per pair on the hi-fi market today and it’s extremely rare to come by.
The difference between WE101D and WE101D-L is pin, WE101D needs to match original WE-style tube socket, while WE101D-L only need flat quadrangle tube socket (like 300B socket).
