[ICOM] Icom 756 and ESD

[Larry Young]

To All; I am almost willing to wager that most every brand of amateur solid state tadios have their share of issues associated with ESD and every nature of spikes that could cause damage. It is the nature of solid state electronics to be less tolerant when the parameters of solid state devices are exceeded. I have owned solid state radios for the last 35 years and have never lost a front end or PA module ever. I have had power supply failures. We all know that power supplies are not that efficient and generate the most power loss and heat.
   I question if anyone knows the percentage of ownership of the various brands of radios. Does anyone have this data? This is how we can best determine the failure rate of a particular brand and model radio.

Thanks for the info. Hope that is the case.  I have a friend who just had a 
746 original die.Turned it on one day and it wouldn't transmit any power. I 
didn't know the 746 original had that problem as well..  Can't say that I 
have ever seen a review of the 756 original that mentioned this problem. 
Hoping to get one soon.
