Hi, I also came into possession of a packard-bell DPA-30 but mine is the 4. Does this mean walnut shell? Did you get the full schematic for it. Buddy is going to the AWA museum and is getting me a copy but I would like to see yours. Love the space-age stereo plaque on it. Used to be a finish sander at AEOLIAN piano factory so it will be an easy refinish
