Two Sleeves of 1950\'s Western Electric 403B - 5591 - Tubes - Scores 80 to 100%
Test Scores Included, Amplitrex Verified.
For best results - before you install your tubes be sure that your power is off, that the tube sockets are tight and cleaned periodically with a product like Detoxit 100%.
All tubes are tested and or matched on the Amplitrex AT1000 digital tester, in Fixed Bias mode.Buy with confidence - I accept 30 Day returns and provide tracking numbers on everything sold and shipped.NOTE FOR INTERNATIONAL BUYERS - needs to do a better job of explaining to buyers about international shipping. When I get the order, I ship to the USA shipping agent, the agent then ships the package to the international buyer. Usually this takes about 3 weeks to complete. Fortunately they haven\'t lost any packages yet. Hang in there it will show up. - Jim
