This seller has not set a shipping cost for Bulgaria. Please contact them to ask about shipping.
Matched pair of vintage 1959 Sylvania 12AU7 / ECC82 vacuum tubes featuring long gray plates and square getters.
These are pre-owned tubes that test exceptionally strong. They are closely matched for both gain and transconductance (mA/V), with well-balanced sections.
TEST RESULTS:
Tube 1
Gain: 17.5 / 17.3
Transconductance: 1.61 / 1.66 mA/V
Tube 2
Gain: 17.5 / 17.3
Transconductance: 1.64 / 1.62 mA/V
Both tubes show virtually identical gain and very strong transconductance. An excellent vintage matched pair for hi-fi audio equipment, preamplifiers, and guitar amplifiers using the 12AU7/ECC82 tube type.
