It's not uncommon to see one of the rectifier diodes shorted.
That will also blow the fuse.

You are right inhere, did the testing here at my work and one of the diodes did give a false signal which indicate it was not working. The testing of the capacitor was not done because the 4700uF was way out of reach of this testing tool.

Did have a master where the 4700uF was increased to 6900uF last week.

Soldering braid and suction bulb's will float or break your traces at some point. Not my thing. A desoldering station here for daily use.

Saves time and prevents floating or broken traces.

Replace the relais if your using passive speakers.

Like to know:

1. Did you noticed any difference in sound between the 4700uF and the 6900uf?
2. What type of capacitor did you eventual use? 

No, sorry I haven't. It was brought in with another fault and replaced the capacitor after measuring.

All these Roederstein caps have the same symptom, they lose contact at the centre solderjoint due to the heat. Hardly visible, but is there, a broken solderjoint. So it must make a difference.

If used a type snap-in from Rubycon if I remember correctly. 

I have the luck here at my work lots of experienced electronic guys are around so they did show me another trick to give a indication if the ROE is wrong.

Nothing broken on the ROE capacitor, but still I'm going to replace it by the Panasonic. Be aware that the tripot on the ROE does have a function, without resonation could occur, that why I think Onkyo has used epoxy in my vintage receiver. Think I'm going the same for the two leads capacitor.

Like to know another thing, can I replace the missing glass panel by a plastic one, like LEXAN or plexiglass???
