Default Re: Revox PR99 Keeps Blowing Fuse

That is the fuse for the 21v power supply to the electronics.
You have obviously got a short circuit on that line.
If you have an Avo meter check the resistance on the 21v line and fault find from there.
Suspect are the Fraco's and riva's caps. Ckeck the suppression cap across the mains input supply, it is behind the panel with the mains socket and fuse holder on it. If it has not been changed, it will blow eventually, and blow the mains fuse.
