RARE VERSION RUSSIAN MILITARY 6H8S 6SN7GT METAL BASE. The tubes are carefully selected and Balanced matched for both triodes with the same test reading: This is the rare military version of the 6H8S, heavy duty metal bases, T-shape plates, two holes in the plate and spring steel plate supports like Tung Sol construction! They have incredible air, image, "rosin-on-the-bow" realism, and powerful yet accurate bass. Very hot testing tubes with great gain, yet incredibly quiet.   The tubes have been tested (No noise, no microphonic) and perfectly matched  (Tube 1:: 102/102   Tube2: 102/102  Tube 3:: 102/102   Tube4: 102/102  ). Fantastic sound!!!  The tubes are NOS-never used.
