Fuse replacement?

Is it correct that there is no option to replace a fuse in the RS130?
But in case there is, what is the value (size, amperes, slow or fast)?

Not possible, automatic fuse

No, i think not. On a picture inside the RS130 i see a construction. One part is described as a 6A thermal circuit breaker… So, it is no longer possible to tune the sound by replacing a fine-wire fuse with AM / SR …

You definitely need the Blue circuit breaker. It will fabulously add to sound quality (just kidding).
A circuit breaker replaces a fuse so you are correct.

Thanks all! Good to know that there is not a fuse functioning as a weak link in a great chain.
