Looking good Kelley! Do you mill the frames yourself too, or have them sent out to be machined?
So on the 73100 Select Direct Micro, for the bridge rectifier (the 4 items near the front of the board), I got a puff of smoke from two of them. What would cause the bridge rectifier to go up in smoke?
I placed the locomotive on the track, it had a weird ringing/buzzing sound, and while doing that sound, I saw the puff of smoke. I looked closely where the smoke came from and two diodes for the bridge rectifier circuit (the front two close to the LED in the front of the board) have these weird bubbles off them.
BTW you have to make a certain number of posts before TRW will let you post a picture. The actual number of posts escapes me for the moment but in good TRW tradition someone will remind me.
