Hello , i found a paire of Sombetzki 120 esl's , and i'm trying to get them to work again.
At this point i want to find out what kind of voltage is coming out of the electronics , because they play but realy soft.
Does any one here know what the voltage should be for this particular esl , and even more important how can i messure it ?
I understand that you can not use a regular Multimeter as it would influence the measurment as soon as it connects , and the very high voltage. I'm not even sure if my fluke would be able to messure 2 or 3 or even 4 KV.
Somebody mentioned something like a tube voltage meter meet i can not find any thing like that anywhere.
Thanks for your help.

Except for the possibility of electrocuting yourself, easy to measure with a 1000 to 1 voltage divider, esp soldered together with alligator clips top and bottom so you can fasten the voltage divider to the circuit before turning on the electrocution current.
Solder together in series maybe a dozen ordinary resistors totalling 100,000,000 Ohms followed by one at 100,000. Then you put your Fluke DVM across the 100,000 Ohm resistor. You can even calibrate it (or establish the correction factor) using a 10 volt, non-lethal source.

Hello B, thank you very much for the quick reply , im gonna show your suggestion to the technician who is helping me with this, to see if he can make this ;-).
If we don't get killed in the next week or so i'll let you know how it went.
Now i only need to fiind out what the voltage should be for the 120's so i can compare it with wath i hopefully can measure later on ;-).

Hi,
I'd suggest t o contact Mr. Sombetzki himself.

Page 11 of the manual shows an egg-crate or luminaire-lens structure. Many thanks to Calvin.

According to attached brochure, bias voltage should be about 3kV.
I also attached an old project on how to build your own HV probe.
For best accuracy measuring ESL bias supplies, use or build a probe with the highest impedance possible.
bentoronto has mentioned 100Mohm as a target, which will work, but 1000Mohm is much better for measuring bias supplies that are only capable of extremely low current.
BTW, if you will only be measuring voltages < 5kV, you can use fewer resistors of higher resistance value and safely stay within voltage and power ratings of common resistors.
