New, factory platinum matched set of four Tung-Sol 6550 tubes. 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.
These are burned in for 24 hours, factory matched at real world voltages and then the test results are labelled on each tube box.
As new tubes, these are covered by the factory 90 day warranty.
This new production Tung-Sol tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.
The new Tung-Sol 6550 has been closely constructed to the original specifications of the triple getter, 3-hole plate version. The build quality is top notch and the price is great, making them an excellent alternative to expensive NOS tubes.
They are matched by the factory at 400V plate, 225V screen and -19.1V bias. Insist on factory platinum matched tubes for best performance.
I have been selling tubes of all types for more than ten years. Buy with confidence.
