Weight
This circuit ensures the poweramp does not shut down completely when a
single power tube failes. You can continue to play, but the affected channel's
output power is reduced by 2/3rds (depending on the type of defect).
Gas developing in the power tubes can cause a momentary short circuit.
The fuse activates, but the poweramp is not shut down!
Often the tube absorbs the developed gas, and is operable after a short circuit.
Usually the problem can be rectified by replacing the fuse, but if the new fuse
activates as well, the defective power tube needs to be replaced.
