I found an HW-16 on Facebook; it was listed by a ham's widow. It is in mint condition and has the original box. The top and bottoms covers have never been attached and I don't have the screws for it. The manual has his checkmarks beside the list of parts. I don't know if it was completed and didn't work or what. His widow had no idea. What would be my first step here- maybe replacing the electrolytic capacitors with new ones? How do I know what size screws to use for the covers? I didn't want to plug it in- I mean, it might work fine but thought better to ask here about logical first steps. It's safe to assume the electrolytic capacitors are all bad, correct? I see Hayseed Hamfest has a kit of caps and resistors for this rig. Should I get that and replace those parts? Any other suggestions are most welcome!
