The repairs are done and the board is on the way.
I could only find both parts at jaycar (locally anyway)
Their catalogue says they carry the BD 649  tranisistors but as mentioned by another member earlier they gave me an equivalent which is a BDX 53C. There are already a couple of BDX 53C transistors on the board from previous repairs. I checked the specs on both transistors (just in case the equivalent had a lower rating) and they were a match.

I checked all other components relating to the faulty transistor (resistors & diodes) all were fine  

I also socketed and replaced the 7407 I.C. that controls the transistor with blown out junction (the one in the photo with it's guts blown out) just in case it was also damaged. Lucky i checked the tiny numbers on the I.C. (With a magnifying glass, my eyes aren't what they used to be)  they had given me a 7404 I.C. which is a hex inverter not a hex buffer like the 7407. There would have been some drams if i had put 7404 in    

sorry if i have bored anyone with my technical bla bla   but i thought i would put it here for any one that may need to repair a Zaccaria driver board.
