CD4013 question

[jdub]

How easy is it to zap a 4013 chip? 

My Elec Mistress stopped flanging & I checked voltages and had no output coming from pins 6, 8, 10 & 12 of my 1024 chip.  Checked pin 1 of the 4013 and also found no voltage- replaced it, and got flanging after bias readjustment.  Then it stopped again- replaced 4013 and the whole episode repeated itself.  Went through three 4013s! 

Could an SAD1024 problem cause this to happen?  I'm asking because I'm not certain of the functionality of the 1024 I have.  I'm taking static precautions for the 4013- what else could cause them to fail like this? Power surge?

Any advice would be appreciated.  Thanks!

is it getting more than 15v on its power supply pin?  Or, could it be the 4013's aren't actually dead, just that opening the box and rummaging around connects a flakey connection?

Once or twice a year someone will post a query regarding use of a higher-powered supply.  My answer is always the same: If you are using it to power pedals with CMOS chips, be very very careful about having anything more than 12v touch the pedal.

Thanks, guys.  It's a 9V Mistress; I usually run it from a battery, but when this happened I had it run from a regulated 9V wall wart.  Since supply voltage never exceeded 9.05V, I don't necessarily think that's the prob unless there was a spike of some sort when I plugged in the wart...
