2x Svetlana 6L6GC / SV6L6GC Vacuum Tubes, Factory Matched Pair, Test Strong

Description

This is a pair of Svetlana 6L6GC that came installed in a brand new high-end boutique guitar amplifier I bought years ago, but I never used, replacing with RCA tubes at the time. They have mfr. date codes of 9852 (last week of 1998?) clear glass, clean pins in white boxes. They were factory matched for gain and idle current and test like new on my TV7.
Please note: I am liquidating a 40-year collection of tubes and other parts for guitar and hifi amplifiers. I have been selling these parts for over 20 years and have earned a strong reputation for honesty, reliability and customer satisfaction on eBay and other sites. All the tubes I sell have been tested for mutual transconductance on calibrated testers and are reported as such, but the results on my testers may not agree with yours. Further, I cannot guarantee tubes against noise or microphonics. Most of the tubes I sell are between 20 and 80 years old and by nature are fragile antiques. For this reason, I DO NOT ACCEPT RETURNS because of the fragility of vacuum tubes and the uncertainty of how they will be used or abused by the buyer. I will certainly work with any buyer to address any problem that may occur such as a tube that arrives damaged in shipping etc. If as a buyer, you feel you cannot agree to the sales terms of my listings, I kindly and respectfully ask that you do not purchase tubes from me.
