Bob Carver C-500 worth restoring and/or upgrading??


Hi...
I have a Carver C-500 that I am the original purchaser of back in the 80’s.
It has been stored well, but has not been used for 30 years. I have a need for a good amp with some power to drive some DynAudio Contour 20 4ohm-rated speakers.
Can anyone "with experience with C-500s" tell me if the amp is worth refurbishing/upgrading? Where I should get it done? ...and a guesstimate cost range? I am looking for good work, not a cheap price. I also respect skilled, knowledgeable technicians... The unit has nostalgic value to me, so if it can compete with today’s solid state amps from a performance standpoint, once refurbed...I want to do it up, RIGHT!
At the very least I will need the capacitors replaced.
Any takers??? (Bob Carver BASHERS need not respond, although I am open to knowledgeable criticism of the C-500 with specific evidence! 😎).
Thanks guys!

So...I am kind of becoming an expert on the topic! LOL! I have had all these "experts" telling me to replace the capacitors, blah...blah blah. The only Carver-authorized location has mixed reviews, for sure. Plus I would be shipping it to strangers...the cost of packing and shipping and potential for damage, etc..etc......so....  I finally talked to an HONEST, open tech here in NJ, who has a killer reputation and he works out of his house. Has worked on Carver before. He said that all the hyperbole about capacitors is horse sh*t! 🐎💩😬
He told me how to test my amp with a voltmeter (and it checked out fine) and I inspected and there is no leakage from the caps..They look brand new...so the amp may work just fine. I am waiting for a Schiit Freya + tube preamp to get here (they are 6-week back ordered)...and I will get some junk speakers to test on in the meantime.  If it doesn't work out, I can take the 80min drive to Ho-Ho-Kus and drop it off in good hands.  I am finally getting somewhere. 😁👍🏼
Thanks for your input!

call and speak with the owner or his son. They do great work.
the restore a lot of stuff.
great work!!

 If your close to Rockford, drive her there. 
I agree with everyone else, Deltronics is the place to fix it back to spec. The only downside is there is a 9 to 12 week turnaround time so be prepared to wait.
OK...I connected with Tim at Bristol Electronics in Ho Ho Kus., NJ..as mentioned above. After my amp testing the Schiit Freya arrived and as it turns out.....my amp works just fine and sounds GREAT! So Tim was correct about the capacitors! 40 years old and kicking badass! 😬
So...I am an extremely happy guy with a fantastic, powerful combo with the Freya and The Carver together. I plan to install/solder-in a new power cord on The Carver, as the original is spindly and about done. Also, the amp has no on/off switch as it was designed to be plugged into a switched outlet on the Carver preamp, (as many amp/preamp combos were of that era). So I plan on installing a radio controlled outlet for it and The Freya (as the on/off switch on The Freya is on the rear of the unit? The remote also does not have any on/off control. That is super inconvenient if your gear is in a cabinet like mine is. DUH!).
I have a Marantz SCAD/Streamer 30n shipping 2moro morning for my set-up, so I am pretty excited!!! 👍🏼
