Greetings!
I need assistance in identifying a semiconductor. It is from a ROAD 220 bass guitar amplifier. The part was mounted on the driver pair heatsink and, in circuit, it is wired across the PNP/NPN driver compliment from base to base. I'm really stumped because of the odd ID, and odd case style. I'm sure it is part of the thermal regulation of the output xistor bias. I'm unsure if it is either a transistor or a diode array.
Google has not turned up either a schematic for the amp or anything that remotely matches the markings on the part. One leg of the device is completely blow off. The drivers and output transistors were all shorted C-E.
Thank you for your help!
