Crown is a famous manufacturer of pro amplifiers for studio use, if it's the same company. This machine looks really well made, probably '50s or '60s going by the design, almost certainly a high end / pro machine judging by the fact that it seems to be assembled from discrete parts bolted into one case, eg. the two pre-amps mounted under the transport with the VUs on there. I'd say it's definitely worth fixing but would require some electronics skills and some specialist parts probably to restore it. I wouldn't fire it up as you might cause damage.
If you are interested in restoring vintage kit then it's a worthwhile project certainly. European machines from that period like the Revox G-36 are highly sought after and not just by collectors either. They sound fabulous when properly maintained and calibrated. Someone like
Electronics Service labs in New England would be able to do this kind of work or else perhaps give you some pointers.
Reel to Reel was a little like SACD back in the day, it was an audiophile medium and you'll find a wealth of commercially released tapes on ebay dating between the 1950s and early 1980s. Everything from Jazz and Classical through classic rock upto Blondie and Elvis Costello. Some of it's pretty expensive obviously but no more so than the records and on the whole it's in better condition as most people who had this kind of kit would have looked after it. You can obtain modern recordings on reel to reel today but it's a pretty expensive hobby
the Tape Project
Of course these machines are also amazing for recording which was what they were primarily designed for and that Crown looks like a stereo halftrack at a guess, so this would be it's main point in life...
