FOR SALE: MULLARD GZ34 RECTIFIER F31 series. The tube is marked with a small Mullard white shield. The etched date code is F31 B9C (1959 March). It tests 102 and 98 on my B&K 707 tester. There isnt much to say about such a wonderful tube. They last forever, seem to produce no noise artifacts and produce a black backdrop for the music to float on. This tube was purchased from Andy Bouwman at VTS as a backup for a Mullard F32 (7 notch) GZ34 rectifier (which was in a Supratek Chenin when I purchased it). The 7 notch tube went for another 5 years and was still strong when the pre-amp was sold recently. I expect the F31 tube will outlive some of us. It will be shipped in an old plain blue box.

Regards Geoff
