Audio Power Transistors - Buying in Bulk

Hi All,

Does anyone have a solid opinion on the quality of Multicomp Pro MJ15003 and MJ15004 power transistors (Newark# 76AH5818 and 76AH5819)? I want to stock up on these parts as I use them quite a bit and the Multicomp Pro ones come in at about half the cost of the other name brand devices. I use these parts for vintage audio amplifier repair and the occassional amp build from scratch. Not exactly critical applications, but I'd like to get some assurance that they are at least worth the money. Otherwise, I may as well just spend the extra and get ONSEMI. Has anyone tested this Multicomp Pro transistors to see what conditions they fail under as compared to the ONSEMI ones?

    Is that a side-by-side of the multicomp and the onsemi MJ15003/MJ15004?
