Psvane WE205D / WE205D-L Rør - 1 Parret Par

WE205D is 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.

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 (UX4).
