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.
NOTE FOR INTERNATIONAL BUYERS - eBay 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
