[QUOTE="Family_Dog, post: 1035530, member: 82"] A rectifier with an open circuit filament will lead to total failure of the amplifier, nothing will work but no damage will occur. If it goes weak emission, the amplifier will play, but poorly, with low volume and possible distortion. The fuse will not blow in either case. If the rectifier develops internal arcing, that is bad and the fuse should blow thus preventing any possible damage, specifically to the HT winding of the power transformer and electrolytic caps in the HT smoothing circuit. Bad! That been said, this seldom happens. -F_D [/QUOTE]
