You've asked, and I've been listening. You all have made my Classic Bally / Stern LED adapters a great success of the past two years. Enough that I've been able to grow internally, and take on a few new to me technologies. This makes things easier for me to release new products again finally. So, TWO new products are now available. These are the often requested LED adapter sets for your Bally auxiliary lamp boards, used in many -17 and -35 series games.
Now, remember, you still need one of the classic Bally/Stern LED adapter sets for ALL classic bally/stern games to convert the main lamp driver board if you're using an original factory board (Altek main lamp drivers are already LED compatible). The AUX boards are for the additional Aux lamp driver boards, if using factory aux lamp drivers.
First is the -52 style AUX board adapters, used in Space Invaders, Xenon, Flash Gordon, Eight Ball Deluxe (All versions), Fireball II, Embryon, Fathom, Medusa, Elektra, Vector, Speakeasy, Mr. and Mrs PacMan. Regular price of $30 for the adapter set

These are a completely revamped design using surface mount resistors, which eliminates all the interference issues that plagued me during early development. Much lower profile, no risk of bottom side shorts, faster assembly, faster prototyping, and more parts commonality for easier inventory management. This is all a huge leap forward here as it makes these designs much quicker to bring from concept to production. Here's the final prototype version, for a sneak peek, final version will of course have full green masking and silkscreening. Plus a bigger 1206 sized resistor for improved heat dissipation and wattage rating.
Now, the next question that always comes up is "Where are the 6803 Adapters?" I have prototypes on-hand for testing. I'm looking for beta-testers who have a 6803 and are willing to trade a free adapter set for photos and feedback. PM me if you're interested. First come first serve.
