Tung-Sol QUAD Factory Platinum Matched EL34B 6CA7 Tubes
A set of four factory Platinum Matched Tung-Sol EL34B tubes. These are factory matched at real world voltages for current and transconductance. The test results are labelled on each tube box as shown. These are difficult to find at a reasonable price, so this is an opportunity to obtain a world class tube at a price that won’t break the bank.
The tubes are burned in for 24 hours, factory matched and then each tube is labelled with its test results.
Comments on the sound quality from the maker: “The Tungsol EL34-B is a higher impedance EL34 tube design with increased touch responsiveness and a unique clipping characteristic with a hint of the 6L6 sound.”
These are made in the Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.
They are matched by the factory at 400V plate, 250V screen and -17.52V bias. Insist on factory platinum matched tubes for best performance.
All tubes carry the 90 day factory warranty against defects from date of purchase.
