I'm working on a Lab Gruppen amp that has multiple damaged components due to shorted outputs. On the list are two ST BYW81P-200 fast recovery rectifier diodes in series. Unfortunately, these are obsolete and I'm looking for a sub. It appears that the MUR1520 would work, even though the specs aren't identical. Could use another set of eyes for confirmation.
