    Hello all, i am having a problem with the pop bumper bulbs burning out after couple of games, from cycling on/off from the spinners. I looked at the voltages off of BR1 supply board TP1 was 5.4 vdc and 3.3vac. I replaced BR1 and still same measurements. Not sure what i am i missing.
    Please inform, tx. Joe

    all good and tight, i also switched the pop bumper bulbs from 44 to 47's to stay cooler, but their burning out.

    all lamps and the pop bumper lamps still work after lamp test (cycling on/off). unfortunately no other lamp driver board to swap.

    Yes, i did revert back to the old school bulbs and they did last longer, but those still burn out. On the Evel game, the spinners cycles those pop bumper lights quickly on/off. Thinking this could be voltage or inrush current problem.
    With the lamp test or lamps constant on, doesnt seem to be a problem. The game and pop bumpers are currently "on" and will have to take a look in a couple of hours.
    Maybe the pop downward movement is causing, but not sure how to verify.

    Tx for your responses, snyper and MrBally.
    More info, just played a couple games without pop bumper caps on to watch the lamps. After a little playing i noticed one bulb getting brighter than the other, eventually burning out. After about 5 minutes more playing the other started to get brighter than burning out.
    As for the LEDs, any mods needed?

    Tx for all the info, i will start with the leds and added resistance. See how that works out. Not sure i want the added expense for new board, but thats a good call.
