Just started building MIDI modulator kit now. Double sided PCB and very close
connections so I am taking care. Especially when I insert a 28 pin IC !
In the meantime that premature break out has started up again in the same place.
Started again when I turned up an unmodulated spark to max so may have to reposition the main break out to avoid the gentle bend where break keeps occurring.
Just found Bach's organ music on square wave on the net but it doesn't modulate the spark. The square wave amp o/p must be too low as my 555 modulates OK. So will have to sort that out.
More news when it all works!
