Hello - nned help to identify Orion / Kortek chassis please!

[markoneswift]

Hi all,

I acquired a Bingo! Korean candy cab recently. Everything has been removed from the cab, except the controls, tube and monitor chassis. I was told by the previous owner that the monitor did not work, hence why the cabinet got stripped of game board / power supply etc.

I believe the chassis is a Kortek KT-2901 but it is also branded Orion on the main and neck board. The tube is a Samsung A68xxxxx 29 inch and appears in good condition.

I have already located a shorted HOT (a BU508DF part) so I'm sourcing a replacement. I would really like to find a schematic or at least find a chassis which is similar. Any help would be greatly appreciated.

Kortek is not my thing but when I search for Kortek KT-2901 I get pictures of a chassis that looks more refined and recent than yours which is very basic and has a late 80s/early 90s flavour. The date on the PTC seems 1995. Other parts will have a manufacturing date too so you can figure out when it was made.

If you have a high resistance reading across HOT collector pad on the chassis (i.e. with HOT off circuit) and ground, you could use a dummy load (60W light bulb) and see if the power supply is working or not.

The design of this thing is completely conventional so schematics may not be really necessary.
