Up for sale is a matched pair of 2 vintage Ken-Rad 6080 dual power triode valves, brand new in their original vintage K-R Tubes / Ken-Rad boxes. Made in the USA, these heavy-duty industrial power tubes feature rugged metal bases, microphonic-reducing triple mica construction, deep black plates, and top-mounted square getters.
As shown in both tubes have been bench-tested on our laboratory-grade Amplitrex AT1000 digital tube testing system. The measured plate current (Ip) and transconductance (Gm) results are calculated against standard factory specifications (100 mA / 5800 uMhos) and detailed in the table below.
