PL519 Valvo Heerlen 40KG6 Matched Pair EAR Used Tested 130/120mA

One matched pair (2 tubes) of PL519 / 40KG6 Valvo Heerlen.

The tubes are USED, but carefully selected, tested and matched from a larger batch of tubes with the same construction.

They were tested on our calibrated Tesla BM215 tube tester under the following operating conditions:

Anode voltage: 150 V
G2 voltage: 150 V
G1 voltage: -24 V
Measured anode current: 130 mA / 120 mA

The pair has been selected specifically for close electrical performance under these test conditions.

IMPORTANT TESTING NOTICE

Vacuum tube testers can use different operating voltages, test procedures, calibration standards and measurement methods. For this reason, readings obtained on another tube tester or under different test parameters may differ from our measurements.

We cannot guarantee identical readings on other test equipment and cannot accept claims or returns solely because another tester, amplifier or measurement method produces different numerical results.

Our stated measurements refer exclusively to the above test conditions on our calibrated Tesla BM215 tester.

The tubes are guaranteed to be functional and to meet the stated test results under our specified test conditions.

Please check compatibility with your amplifier before purchasing.

As is, what you see is what you get!
