Default Re: Fuses keep blowing on Rotel RX400 amp

Unless I'm misreading your notes, there is a short-circuit between the +ve and -ve terminals of the rectifier (I'm assuming that a reading of 0002 on your DMM means zero ohms) If this is the case, the fuses will keep blowing. The next thing to check would be which component is s/c. - it could be the bridge rectifier -the only way to do this is to desolder the =Ve & -ve terminals of the rectifier, then apply your DMM, set to it's lowest Ohms range, directly across the rectifier terminals.
