Hi,
Got good answers a couple of years ago on this issue but never followed up unfortunately. Now I decided to finally do something about it.
Bought new fuses, F2 (?) for the PSX. Both needed replacement. But didn't help, still silent and the new ones are OK. At the start up it was this nasty smell again from the PSX. Any further advices what the problem could be? Is it possible to easily stop using the PSX and only use the amplifier itself?
Background:
Have Cyrus Two with PSX, working excellent since 1992 until I managed to shortcut one of the loudspeaker cables (don't ask me how...).
Now it is dead, well both the Cyrus Two and the PSX light up when you turn them on, but no sound at all. I suppose that means the fuses are OK?
There was a light smell so probably some components got damaged. When this occured I haven't started to play so there was no output to the speakers, it occured as soon as I switched power on.
Is also the amplifier damaged, or only the PSX?
Grateful for all advices.
Regards Robert

Chances are people will say that i'm not a nice guy but what you're asking is just incredible (in the literal sense of the word).
It's as if you were on another planet with your car broken down, telling us that your dashboard is on but your car won't start and asking us what the breakdown is.
There are really very competent people here but to my knowledge , no diviners.
Open your devices, take pictures, drop them here and people, maybe myself, can guide you for the rest of the operations.

In a nutshell what HuggyGood has written.
The Burning smell is an indication all is not well. The use of the power LED's being lit may only indicate power on that winding of the Transformer is available.
Taking the cover off depending on what Cyrus model is you will need to exercise care, if they are plastic cases the plastic will be brittle with age and you need to gently ease the pieces apart and then take the images to post in the forum.
A shorted loudspeaker is likely to have damaged the output transistors, possibly driver transistor's and maybe a few other components. As to the PSX I haven't seen a diagram so cannot comment. But smell is not a good indication.
There is a thread here I seem to remember regarding output transistor replacement. Search for Cyrus 1 or 2 repair, or blown transistors

No raymond, that's really what I meant, it's surreal.

The YouTube channel Myalbatech has a number of Cyrus repair videos that might help.
I agree with raymondj and would start by checking the output power transistors. They are at risk if the loudspeaker cables were shorted. Beyond that I would be guessing.
