[ICOM] Lightning vs PS-125

[Larry Young]

Mike and all: Our local radio club program this past Tuessay evening was about station grounding. While the audio is not available, the pp presentation is here: www.rars.org/  scoll to the middle of the page to grounding. The file is about 50 megs. After the slide asks  Questions, there are additional slides listing all the references including more information.
Regarding switching supplies. They usually work properly or they do not work at all, as there are no Pass transistors to short as with analog  supplies.The possibility of damaging a radio this way are usually nil.

Mike,

Can you fill us in on the details when you get a minute? i.e. Can you tell
where the lightening struck? Was an antenna connected? Was PS-125 plugged
into wall outlet at the time?  CI-V? Is your station grounded? If so, how?
Just curious. 

Oh, yeah - you may see stuff starting to fail weeks/months afterwards due to
latent stressed electronics.  That happened in our neighborhood a few years
back.  Tree took a hit about 50 feet away. Everything was fine for about 3
weeks then the DVR went bye bye, then the answering machine.  Neighbors
reported similar problems.

Thanks and sorry!

My station was whacked Sunday afternoon, and it got most everything. There
are matching burn marks on the Pro II and the PS. The Pro II is fried.

The PS-125 shows 14.35 V.  How can I determine if it's safe to use?
