Axiom Home Page Forums General Discussion Technical Questions My Rotel RB-1080 lest channel died

Some kind of junction for the four round things under it, I reckon. I haven't a clue what 98% of the stuff inside this thing is..... Sure is built stout though. Nothing flimsy or cheap in this sucker.

the round things are large capacitors, and the plate on top seems to be connectors (+ -)

Is it back in service Mike?

You are forgetting to add the Rotel to your Rotel... That will fix everything.



I would stay away from the HOT one though as it can cause overheating.

Silly me. I didn't see the caps underneath the plate.

Need to find a fuse. Work and all keeps interfering with my business hours shopping....

I think you can buy them online.

Here are some "high end" fuses. Supposed to make a difference.

Not in a million years will I believe that a fuse will improve the sound of your system, but hey, some people sware by them.

Michael, can you take a close-up of one of those blue capacitors (the big cylinders) on the amp board? In your second photo it looks like there is some black stuff where it meets the PCB. Rotel, or more likely their 3rd party manufacturer, used a corrosive glue under these capacitors which will leech out over time and start to damage the parts around them. The blown fuse might suggest that some corrective action is required.

That gold plate is likely a piece of plated copper. It is the central "star" ground point for the amplifier, and all ground returns (transformer centre-tap, safety earth, main power supply capacitors, amplifier PCB, input stage PCB, speaker negatives) will all connect to this bus plate.

Indeed. It must be nice not to have to worry about fast transients, surges and ring waves on I/O in audio. Then you can get away with a pseudo star ground.
