Namco System 12 - Help identify part

[SmokeMonster]

I have a Tekken 3 board with video issues, and I found a missing part labeled 5R6K on the top board. Could anyone recommend a replacement?

Also, is there any way to adjust the video level on a System 12? System 11 has a pot labeled "video line adjust" but the 12 doesn't have anything except an arrow pointing to the "video level" solder pads. Can a pot be soldered there?

Here is a known good Namco System 12 that I have:


And here is the board missing the 5R6K component:


Normally I would just look up the board's schematic, but there is none to be found for System 12.

I found both of my answers here, care of l_oliveira in 2013!

RV201 is intentionally empty. leave that alone. On System12, video level is controlled through software, as the CPU can send software commands to the SONY (CXA 1779 DIP chip) video amplifier chip on the large NAMCO board, using a I2C bus. :awe:

L202 is 5R6K -> http://uk.farnell.com/multicomp/mcnl453 ... dp/1864335
C2 is 47uF, 16v.

This is its equivalent from Digikey, and here is a better rated one by Vishay.
