Nice conversion George. DCC ready makes things a lot easier. Back in November I converted a pair of older Athearn Genesis yellow box SD75M diesels (BNSF H2) using the TSU-PNP deocders because these didn't have any DCC interface on the light boards. I also used your 28 mm speakers as well, but I screwed them in because I didn't know about your adhesive gaskets (that would have made this conversion, plus the conversions of a FP45 and a SD45-2, easier).

Watching the video it looks like you have some new material for the next blooper video.

Be careful if you do use the screws to mount the speaker. One of the screws will hit the drive shaft if you go too far.

I know its been a year but why does this video feel rushed like you just wanted to get out of there
