Lightly Used, Like New Batch of 2 Tubes ECC81 12AT7 1965 Mullard Mitcham Production. Date code 652 R5G1 and R5G3. Mullard Old Shield BVA Logo. Labels are fragile and not perfect as it was common with tubes from that era. Test scores are not close enough to make a matched pair.

These 1960s Mitcham tubes are more desirable tubes than the late production 1980s CV4024 and M8162.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt. 65% = 3500 mmhos for 12AT7 on this tester.

Test Scores: 6000-7200, 7600-7400 mmhos.

$50 this Batch of 2 tubes as shown.
