I have a yamaha rx-v467. and i have lost the fuse, Now I do not know how much ampere it should be on the replacement fuse.

This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic. 1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

Hi there,
Try the codes on this website here:

Just scroll down to where it says Pioneer. Let me know if those don't work.

I think so...I looked at the specs on this and it does not have provisions for 240V. You're going to need a step down transformer from 240VAC to 115VAC.
