then replace the op-amp (if it's a JRC4558, replace it with an LM358), the DAC (digital to analog converter) (not sure what this one needs but I'm sure it's all over the place, esp KLOV forum).ģ) and lastly jump any of the 64 pins (with 30 awg KYNAR wire) that have lost connection between their corresponding points (or those that have an ohm reading higher than 1.0 Ohms (supposed to read between 0.5-0.8 ohms).Ĥ) Then use a nice rustoleum lacquer spray paint to make it look original. So the best way to make sure it lasts a long time is (and I highly suggest going to the KLOV forum for info).ġ) you must remove the sound amp (use nothing but chip quik SMD removal kit as it's the EASIEST way to remove it without damaging ANYTHING- sorry for all the caps)Ģ) then you must remove the capacitors (using two irons or chip quick).
I repair more and more of these as the original capacitors used on ALL of them from the 90's ALL leak and erode away at the traces and solder pads on BOTH sides of the amp.
Here's a good one, watch out for the custom sound amp (big black ceramic IC in the corner of the board near the Jamma edge).ĪLL Konami PCB's with ANY version of the custom sound amp (X-men, Xexex had the same sound amp - Lethal enforcers, metamorphic force, and others had similar amps but different from X-men).
