Sorry to hear about your husband. He spent years accumulating his collection and spent a good amount of your assets on it. Good news is that this is worth good money if it is in good working condition. Don't dump it in a huge rush to a reseller and leave a lot of money on the table.
If you have the manuals and boxes, you might also have the receipts. Get in touch with someone fairly local who he bought from and see if he will sell them for you and take a 20% or so commission, so he has interest in moving it for good money. They also generate additional traffic for him. If he is trustworthy, let him take all the stuff out of there now and store it. I've been charged 20-40% for the service. I regret doing the 40%, but I was really urgent in wanting the piece replacing the box I was letting him sell. He wants to make 40% on anything he sells, new or used. If you don't sell it one by one (or very small lots), you will take a hit.
You don't want Craig's list - it is filled with criminals, and you don't want to sell to people like us directly, we'll drive you nuts.
