Yamaha CR-450 help

[avionic]

My local electronic store only has a 4amp and a 10amp. Would the 10 amp work? Below is the data sheet for it (RBV1004).

Sure would..

Good news. I was able to get the part locally (6A 250V) and the unit fired right up without channel fuses installed first and the fuse did not blow. The DBT didn't light up until after I installed the 4 fuses for the speaker channels and it barely had a glow to it. I tested the unit on headphones and it works great now by itself with no DBT. Tomorrow I will hook it up to some fully restored Dynaco A25's and give it a whirl to make sure it plays with speakers. One thing I did notice that I did not check when i first recapped the unit is that someone had installed 10amp fuses in the speaker channel slots and they are supposed to be 3A. I only had 1.5A so I threw those in just to be on the safe side. I will buy a quad of 3A so everything is up to spec. I will also check bias again and go ahead and add new thermal paste to the outputs since I removed them for testing.

Thanks again for your help! I have a feeling this unit is going to stay in my possession and not go back to my cousin.

Probably a wise decision.
