Hi. I am trying to get my first Burst Gen going and running into some problems. When I have
have all the chips in the 4017 gets really hot and twice blew a crator in the chip! I have
checked the active parts Diodes , Transistors and they are fine. I have soketed all the chips
and tried different manufactures. When I remove the 4017 The clock works and trigger
through works. As soon as I put back in the 4017 the clock never makes it to pin 14 of the
4017 and it gets hot. I have checked the traces and for shorts etc.
Richard did metion to me to get all TI parts. I have a TI 4017 and I am awaiting a TI 40106to
see if that solves the problem. But from what he told me and what I have read on the list it
seemed that a chip mismatch would cause false triggering etc. But this seems to be
something else?
I have replace the LM358 with a TL072 and LT1013. No difference. Please help!
Thanks, Charles.
