I got my Wild Fyre all working great now. The only thing I don't like is the annoying sound when I turn it on.

Is there an easy way to get rid of that sound?

Thanks

I found a photo of the board before I re-installed it. I'm guessing it's a rev A because the sticker says "A".

I also found this service bulletin but I'm not sure it's related to the sound on startup.

And I found an old post from Pinside that is related but the OP never said he fixed the problem.

I didn't want to remove the board until I was ready to do the mod. So I checked my inventory first. Sure enough, I don't have a 3.3uF capacitor or 47K resistor. Nothing even close. So I ordered the resistor from GPE but he doesn't have a 3.3uF cap - but I understand 4.7uF will work. I ordered that instead. Unfortunately, he's on vacation so it'll be a few weeks before I get my parts.

I'll let you know when the parts arrive. Meanwhile maybe I'll just mess with the oscilloscope and that old MPU. Maybe I'll learn something.

Thanks

Closest electronics store is on the other side of St. Louis. About 40 miles one way. If it was keeping the game from playing I would make the trip but it's just an annoying sound on start up. I can live with that for a while.

Besides, I think I have a Williams Black-Out coming this week. That will keep me busy (and happy) for a while.

The same bulletin is listed on the Dracula game. Wild Fyre was made in 10/78 - Dracula was made in 1/79.
