Yukon 28041 Binocular - Answered Questions & Fixed issues


Hello, let do this. IR illuminator has a montary switch, that is when you push it comes on, and when you release it the IR goes off and it has a red LED to indicate the IR illuminator is being activated.

When you turn you binocular on there will be a green LED activated. This switch is DTSA---double throw sing activated. That is, one throw of the switch it turns on the binocular, the throw will turn off the binocular.

Also within the control panel there is timing circuit to keep the IR illumniator on for ten second the shuts off. Make sure you have the right switches etc. Let me know, then we can brain storm on this matter. stewbison

Hello, most of these night vision devises are repaired by the companies that offer to sell and service. It almost impossible to find someone other than the dealer to repair them. You try Morrision Optic they have big web page on the Internet. A little warning here. These companies they sell NV devises are not necessarily the manufacture of these NV devise. Russian make a lot of these NV devises for US NV companies.


I repair them also but it hard for me to get parts, and I can make other parts if I can find some dealer that will sell me parts For a 1st generation cheap Russian image intensifier tube will cost about $175 each and sometime I can get them cheaper. GB....stewbison

Here we go. Take it to electronic repair facilities. See if the can replace the LED IR. Now if they want. Call Yukon NV Optics and see what the charge, normally these companies have flate fee they will charge. They really don't make it easy for the owner to repair these NV binocular. Basically, the binocular will almost be totally taken a part. stewbison

Hello, don't worry about it. It is HV to the image intensifier tube. The battery voltage goes through control circuit then to ccfl inverter (here is were dc voltage is switch on and off and switch dc voltage is step up by toroid coil that has two input and only two out puts). By impulsing the coil with two different switch dc voltage on the input this make the current lag the two different phase voltage by 90 degrees. Here is where the strange noise is coming from. The toroid coil is encased in iron case and if half of this iron case is loose, it makes case vibrate so the noise.


Now, the voltage come out of the toroid coil is switching dc (one could call it AC because that what AC voltage is, it switch between positive to negative) this voltage is about 300 to 900 switching DC voltage. This voltage will be applied to a 1/2 wave voltage multiplier (this voltage multiplier with have anywhere four four stages to 10 stages depend on what the input voltage to multiplier is.

Low the voltage out of the ccfl inverter the more stages the multiplier will have.



Now, the voltage multiplier will double the voltage per stage to need image intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever one wants to call it. This voltage will bit you but it doesn't have a lot current associated with it, the current would be in the 10 to 15 ua (micro-amps) 1/10X6 amps.



Now, you know. GB...stewbison

Value depends on its condition and and type (upright, baby grand, full grand etc.)
Serial number suggests around the year 1900 but certainly before 1910
