TESTS CONDITIONS (datasheet)

DUOVAC RADIOELEC 
 T(Va=100V Vg1=-2V Ia=14mA) P(Va=170V Vg2=170V Vg1=-2V Ia=10mA)


HICKOK TV7D/U 
EV9-1086 B34 C min=36 
EV2-6371 B19 C min=34 

Please note that HICKOK is not a laboratory tester, though it is very well calibrated...
HERE is how I calibrated mine following manual services specifications. I calibrated it to respect the low of the scale for filament... High voltage on filament would damage it...but gives higher values...
0.6 (065-0.72)   -->0.65V ; 1.1 (1.06-1.16)  -->1.14V ; 1.5 (1.26-1.42)  -->1.30V ; 2.0 (1.90-2.10)  -->1.95V ; 2.5 (2.56-2.88)  -->2.77V ; 3.0 (3.25-3.60)  -->3.25V ; 4.3 (4.30-4.75)  -->4.55V ; 5.0 (5.15-5.68)  -->5.49V ; 6.3 (6.20-6.80)  -->6.47V ; 7.5 (7.32-8.10)  -->7.45V ; 10 (9.60-10.80) -->10.03V ; 12.6 (12.1-13.3) -->12.25V ; 20  (19.0-21.0)   -->20.50V ; 25  (25.3-28.0)   -->27.65V ; 35  (35.2-39.0)   -->38.09V ; 50  (51.5-57.0)   -->52.80V ; 75  (74.0-82.0)   -->74.82V ; 117 (115-127)    -->116.5V
If needed, i can share all other tests calibrations I get (129.5V/130V +o-3V ; 41.35V/40V +o-2V ; 4.21V/4V +o-1V ; 56.5V /56V....)

EUROPE COUNTRIES, YOU CAN ASK FOR MONDIAL RELAY DELIVERY SERVICE. IT'S LESS EXPENSIVE THAN LAPOSTE, ASK BEFORE PAYING IF YOU CHOOSE THIS SERVICE.


TUBES ARE GLASS MADE, THEY ARE FRAGILE. IF YOU SELECT A SIMPLE "BUBBLE LETTER" FOR THE DELIVERY, I WON'T BE RESPONSIBLE IF THEY ARE BROKEN... YOU ASSUME ENTIRE CUSTOMS FEES.
