Well i've got the strobing sorted just replaced the 12 most frequently activated inserts with regular #555's out of the 50+ leds i have under the playfield and the strobing effect has dissapeared,looks sweet the way the old bulbs and the new led's merge throughout the playfield,the led's without a doubt make the machine look fantastic.took a couple of pics but it looks very different in real life,a picture cant really capture the way they feel.
