Leonard, welcome to this wacky world.
In doing a quick search of your Fathers gear it's apparent this is from a period when some great designs were created but the market was small. It's easy to say that since then much has changed and so have the improvements. Still, nostalgia may play a factor here.
The value may be subjective. You've already waited thirty years, I'd strongly suggest you take your time. Gather as much knowledge as you can via the internet.
On a more professional level you might want to get some input from Art Dudley (try Facebook or Stereophile).
There is someone out there who would love to own this gear and pay a fair price for it. The trick is in the advertising. One method would be to list the entire set here or on eBay with an incredibly high reserve price just to see what kind response it gets.
The idea is you want this stuff listed for enough time so that particular collector has a chance to see it listed.
