Just picked up some old Monitor 10s with the Peerless tweeters. The previous owner told me that when he got them each speaker had a different fuse. One had a 10 amp while the other had a 3 amp. Playing it safe he decided to run the three amp on both speakers. I just blew both fuses turning up my Sansui 7070 to about 11:00 so I need to replace them.
