Having recently toasted a couple of op-amps in my ten-tec 1202
SWR/Wattmeter by adding reverse polarity, I would like to mention the
tip of using a Bridge Rectifier to prevent this from happening in the
future. Wire the power jack to the AC input and then hook the +/- to
the appropriate spots in the project., a simple solution that cost, me
less the $3.00 and would have saved my $6.00 and about an hour of my
time to replace the to op-amps.
