Rotel RB-5000: Need a diagnosis

Hi everyone,

I just received this Rotel RB-5000 off of that auction site and I need some guidance and ideas from all regarding getting this monster back on it's feet. This size of amp is foreign to all of my previous amateur attempts at repair so any help is appreciated. If it ends up being too complicated, I may just find a technician locally to take a look at it.

Here's the problem:

-Protection circuit engages pretty much immediately when the speaker selection is made. Seems to engage the protection circuit quicker when B and C relays are engaged.

-One of the fuse holders on the right side (power supply or drive boards???) is broken off. Will test continuity tomorrow or next week.

No output since protection circuit is engaged.

Any help would be great. I have read that these amps are rare as hen's teeth so it may go to a technician who would be more comfortable repairing something like this. Power rating says it draws 3200 max watts (!!!), 500 watts into 8 ohms and 950 watts into 4 ohms!!! And yes, it is extremely heavy to carry. It dwarfs much of my other audio equipment.

Thanks for the help/advice!

Anyone brave enough?

Sorry can't help with the diagnosis but that's an impressive looking beast.
the POWER amp... cool.

I'm trying to figure out how many were made... I don't see them for sale all that often. It's an impressive doorstop at the moment. Each of the two toroidal transformers is about the size of the single Pioneer sx-1980 toroidal. The main caps are quite a bit larger than a standard 12 oz soda can.

Everyone's yellow belly is showing, including mine Next week, it's going to a local qualified doctor.

Man, even if I could help you I'd be too busy drooling! What a beautiful amp.

If it was mine I would not do anything unless I knew exactly what I was doing.
It´s old, powerful and might contain unobtainable parts. All that equal up to a lot of potential disasters.

I wish you the best of luck in getting the monster up and running.

Did you have the legend fix? How does it sound?
