Up for sale is a matched quad set of 4 vintage General Electric (GE) 6080 dual power triode valves, brand new in white boxes. Made in the USA, these ultra-rugged military-grade tubes feature heavy-duty metal bases, internal rod support construction, deep black plates, and top-mounted ring getters for superb stability, durability, and high-end audio performance.
As shown in all four tubes have been bench-tested and labeled. The measured plate current (Ia) and transconductance (mA/V or uMhos) results are calculated against standard factory specifications (100.0 mA / 5800 uMhos / 5.8 mA/V) and detailed in the table below.
