Photo's of my sound install Tsunami sound in a Bachmann GP7. Milled top of frame to fit keep alive caps since board is installed up side down.  Loco runs good and sounds good.  Joe

Very nice

Exactly which SoundTraxx decoder part number and speaker part number? I am sure some here will be interested.

I have seen questions about sound in some of the Bachmann diesels as some of them run quite well.

Yeah, cost more than the loco but you get what you want. I have done similar installs.

The decoder is part # 828020

The decoder is part # 828020 and speaker is # 810054 1" diameter. I like this decoder even though it's for the Bowser F units because the caps are built into the decoder. I have done one on a P2K SD7 . Joe
