As a result of an disagreement with some lightning I lost my CT-17... 
The MAX 232 chip literally lost its top!

The good news is it was easy to diagnose!  L3 & L4 also blew 
apart.  I'm sure there are other components also that lost their life 
in the pursuit on my hobby.
I have 2 questions:
1: Jameco has the Max chip however there are 3 models listed:
MAX232ACPE  +5V mulit channel drvrs/recvrs C-temp
MAX232CPE    5v 200kbps, multichannel
MAX232ECPE  +/- 15v ESD-protected, n+5v RS232 trans

Which is the correct one?

2:  The surge appears to have come in on the Verizon FIOS line.  Is 
there anyone familiar enough with FIOS to answer a question off list for me?
