Two good strong US-made General Electric tubes. halo getters. One is the white text ECC83/12AX7, the other a 60s tube with tall ribbed plates and red printing. they are not an identical pair, but test well and have sounded good and performed quietly in guitar amps. Tubes are tested on a B&K 707 mutual conductance tube tester recently serviced and calibrated by Mike Mabry in Woodland, WA. Mike has been working on this series of testers for many years. Results tested as follows, for each side, where the first number is a scaled Gm and the parenthetical number is life rating; a Gm rating of approx. 66 or higher is considered “good”: red: 92 (85) and 98 (95)white: 91 (88) and 88 (84) The test ratings on this type of B&K tester may require a bit of explanation. Their “life test” is considered “good” if the meter rating is within 25% of the Gm rating. e.g., a tube with a mutual conductance (scaled) rating of 80 would still be passable if the life test registered a 60 on the meter. Most of their test settings correspond with a 0-120 scaled reading where the “good” area is about 66 and higher on the meter. If you want to combine tubes for a shipping discount, this is possible if you wait for an invoice before paying for any winnings. THANK YOU for looking!
