This replaces the original 1.5K pot 40X0590-017. .25 Watt 350VDC Maximum operating voltage 20% tolerance. 2.5K pot that will fit the board perfectly and can be mounted on either side to make adjusting it easier and safer. This pot will work on all the versions of interface boards for the K4600 & K4700 P297, P298, P302, P305, P305, P306, P307, P308, and P317. If you have a P317 PCB you may need the vertical mount version of this pot which is the P1027 in our trimmer potentiometer category.

These work great on the interface boards on my k4600 monitors. I solder them on the opposite side to have easier access to the black level pot while the monitor is on. No issues.

What can I say, this is top-notch I love putting this on the boards because it just makes everything easier when working with your K 4600. It may not be necessary but once you put it on you’ll understand if you can make life a lot easier 🙂

Critical potentiometer to replace when working on your K4600 monitor. A few of these original pots tested bad after desoldering them.

The black level pot literally disintegrated when I tried to turn it. I got this replacement from arcadepartsandrepair.com and all is well. Thank you for helping to support the community of arcade game collectors.
