SOURCE: KEEPS BLOWING SOUND FUSE

When you refer to the "sound fuses" are you referring to the speaker protection fuses or the power supply fuses?

SOURCE: the two 5 amp fuse inside the amplifier keeps blowing

Hi,

That must be the inrush current.
Maybe you are using the wrong fuses.
Please check if those are fast or slow types.
You need slow types.

Good luck,
Gerard

It seems you have a short circuit in your unit. Further attempts at switching it on are not advisable as more damage will occur. Get it checked out by an electrician who can test from the plug for a short circuit.

Might be helpful to know which fuse. This may help: https://fuse-box.info/

If is a good idea to list brand, model and year of a vehicle in a post. That said, maybe these links will help although some are more technical DIY than your query is asking for:

Connect your Denon outputs to the Realistic main inputs.
Connect your Realistic main out to the Rotel tuner in.

Connect your Technics out puts to the Realistic Tape 1 inputs.
Connect your tape 1 out puts to your Rotel cd inputs.

And you should be good to go.

The fuse keeps blowing in my amp, changed the fuse several times but just keeps blowing!!!
You have an overload in either the power supply section or Main amp section. Culprits in the power supply are the transformer, the Large Capacitors, rectifier, voltage regulator.
In the Main amp anything on the heat sink.
Look carefully for burnt or damaged parts. If there's more than one fuse, follow the path of the one that is blowing it might lead you to the suspect.

Problem with Rotel RA 870
Since it is a Rotel, it is a good unit and worth fixing. At this point, you need to take it to a good repair shop and let a qualified tech look at it. There are no user serviceable parts inside and if you go poking around in there, you WILL make the problem worse. Rotels' are nice units and represent a good value in stereo gear. Take it to a reputable repair shop that repairs Rotel under warranty. If thats not available to you, then a good repair shop should be able to get you going. Good luck...Rob
