Description Technical Specs
 
SOLD only as singles - these tubes have mismatched triodes. Not an issue in many applications . DISCOUNTED since this batch tested  lower than an average Brimar CV4024 from the same era.

Brand New, MINT NOS NIB Mid 1960s Brimar Military Production CV4024 12AT7WA tubes with Black Plates and copper posts. Etched STC Production date codes. Made in England. Relabeled and boxed by Tronix as 6201. Very desirable 12AT7/ECC81 type tube for both Audio and Guitar applications.

These tubes have identical construction to Brimar 6060 T Series Tubes (Item 10). Sonically we cannot tell the difference. Very likely, civilian version of this Valve was marketed as Brimar 6060 with T(Trust) Series Logo. Both of these tubes have very particular black plate construction with copper grid posts, different from the later production Brimars.

Tested and matched on Hickok 752, just recently calibrated and modified by Hickok expert to all Solid State to eliminate drift. However, on average 12AT7 measures lower on this 752 than it should.

For comparison, 12AT7 measuring 4400-4400 on calibrated Hickok 600 measures 3300-3300 mmhos on this 752. Average new 12AT7 on Hickok 600 is 4000 mmhos. In other words, actual test scores are higher than what we have noted on the tube boxes.

Single Tube = $25.
