I'm working on a Sony KV9000UB with a blown line output transistor. I'm trying to find an equivalent of the 2SD625 line output transistor. I have tried a few high voltage/power darlington transistors and the one that gives the best results is a BU931T but it runs hot. I have a working KV9000 and the base waveform is quite a bit different with the BU931T in place of the 2SD625.

2SD625 is available on line but quite expensive, so a modern equivalent would be nice.
