Hi,
I'm working on a 707 with no midi out. I suspect Q6 which is a 603 58F - does any one know a suitable replacement & where I might source one? Could be either said transistor or IC3 which is a HD14584BP hex schmitt trigger - again, anyone know of suitable replacement? .. or perhaps the cpu is failing somehow but I doubt it. I can't scope any of it as I cant afford one yet, so my limited skills have narrowed it down to these components.
Thanks for your help
