Do yourself this favor too:

Check everything in the circuit of the blown transistor. Especially on Data East pins if the fuse was ever over rated, the pre-drivers can go bad. Always a good idea to order 1-2 of everything in the coil driving circuits. Spending an extra $2 now for a parts collection is better than spending $2 plus a ton of shipping later.
