Hi all,
I'm building a drawdio, using this circuit layout: http://www.2ne1.com/files/3913/0968/4001/tracks.jpg
However, I have 2N3904/3906 transistors instead of the 8550 & 8050 transistors suggested, do you think this is OK?
Also, I was originally planning on using a 9V battery so the sound was louder, but this is making the board get very, very hot indeed. Is this a sign I've shorted the board somewhere?
Thanks
Dave
