I have been given a soundcast outcast 410-4n, components Q304 and D12 are missing. Can anyone out there help me with a picture, component markings, or a schematic? It will be greatly appreciated.

I took one of these completely apart. I can't get any sound out of it. It's getting power but the amplifier supply may not be working. All caps and basics look fine but I don't know how to test everything. Need a photo of a PCB?
ian cook, your battery sounds fried.
Hope this help.
Can anyone tell what is the R25? It is Z41 ou 741, please help here!

I thought it would be easier to read, it's 4675
R25= it's 241 (240 Ohms)

@aaron67442 post some good pictures of your board and the components etc. with your Question. That way we can see what you see. Soundcast is a marketing company so I bet they do not make the products. The particular circuit boards may also be used in other devices. that is why we need to see what you got there. Adding images to an existing question

Thanks @oldturkey03 , I just added an image. I googled the board PN, i've tried looking up patents, etc. I did not find any patents in Soundcast Systems Inc. name, which makes sense if it's more of a marketing co. This unit does seem specifically designed for this application, but that's just speculation.

@aaron67442 do you have an FCC ID number on your speaker? Anyhow, do you see any markings on Transistor Q304? Looks like an SQT505 package. Some of those are hard to see and you may need to use a flashlight and angle the beam on it?

@oldturkey03 The parts are not present, it was given to me after someone attempted a repair and the two components in question are missing. The locations are highlighted in yellow with red arrows pointing at them. Q304's location is north of the transformer, and is an SOIC-8 package. D12 is below the transformer and seemingly is a TO-220 package of sorts. I added an image with the FCC. Thanks for the assist!

@aaron67442 Oh okay. That makes sense. Okay, now we really have to try and find those components.
