USED - Single Tubes with IMPERFECT TEST SCORES Rare 1956 BRIMAR 3-MICA CV455 12AT7 Black Plate with Square Getter. Military markings and Brimar etched date codes on all tubes. STC production, made in England. These 3-Mica tubes are rather obscure and some of the best from the Brimar 12AT7 family. Tubes are packed in white boxes from bulk box.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester. 65%=3500 mmhos for 12AT7 on this tester. From the same lot of Item 837 except that these tubes have imperfect test scores (low scores or more than 10% mismatch between triodes). Tubes should still work fine in many applications.

Single Tube = $25.
