I've had a Mac Plus around here for a while that I built up into something useful from the remains of two non-working systems, and the one problem I have is I haven't any sound! Upon startup I just get static for a second, same when using headphones or speakers externally except light static remains. As far as I know this has no modifications except for a 4 MB ram upgrade, however I had no sound before I did the upgrade.

Here it is, doing a whole lotta nothing. It does work despite the obvious such as I haven't made a boot disk and I don't have a keyboard...



Here's a picture of the analog board, still in place:



And here's a picture of the motherboard:



I have a feeling the solution to my problem is going to be a recap, but I figured I would see if there's anything else I should check first.
