Well looks like I can use Ceramic Fast blow with High Breaking capacity after all.. It is to bad that the Littelfuse series 285 does not have a fast blow option. I am going to give the Littelfuse series 216 ceramic a try for my speaker rail fuses since they are fast blow. Note the original fuses are glass. My other power fuses for main power and tubes are slow blow so I will change them to the series 285. Note the fuses that came with the amp were ceramic gold plating. Will report changes here.
Thank you all for your support.
