1. Remove the LEDs and use florescent lamps #44 as intended. Pros: No mods needed and will have a retro look. Cons: Run hot and draws the most current, also not as bright and can heat up and warp insert plastics.
2. Add a resistor to each lamp socket. Solder a 470 ohm resistor to each controlled lamp socket under the playfield so that the lighting circuits see enough current draw to stay latched on. Pros: Inexpensive ($2.50 for 100 resistors shipped) Cons: May take hours of soldering.
3. Buy 3 small daughter boards that attach to the original lamp driver board. These boards have resistors built in, saving the time of soldering them at each socket. Find boards at:www.siegecraft.us cost around $50.00 for all three. Pros: easy to install, low cost and can be easily removed and reused. Cons: Cost, some soldering and more connections that can go bad and if you remove the board you need to remove the LEDs.
4. Replace the lamp driver board with an alltek "Ultimate LED/Lamp Driver Board" for $120. Pros: This board allows you to use LEDs and gives you an entirely new lamp driver board. If you old board is missing, hacked up, burnt or corroded, this is your best option. Life time warranty too. Find it here:http://www.allteksystems.com/products-mpu-replacements.html#lamp Cons; Cost, some soldering, if you remove the board you will need to remove the LEDs.
I elected to go with option #2. I soldered a reisstor to each controlled lamp socket. Took about 1.5 hours of time. Cost was $1.25 for 50 resistors. I can remove the resistors if I ever want but don't see that ever happening. The LEDs look great and work very well. I really like the look of the LEDs on this game.
