[R-390] THIS REALLY SUCKS!!!!

[Steve Toth]

I have a Hakko 808 and second what Leigh said.  I originally bought it so I could replace the 45 pin  final power amp IC in the Onkyo stereo in our family room which I blew out when I keyed up the mic. on SSB while my wife was listening to music and the long speaker leads were not filtered/choked.  Whammo!  RFI pickup blew the amp right out. 

When I replaced the stereo power amp IC the Hakko did such an amazing job of removing the solder on the close spaced PCB connections that the defective power amp IC literally fell out of the board when I unsoldered the last pin.

I have since used it, among other things, to replace an open 4Khz filter in one of my R390A's.  It worked great.  All I had to do after de-soldering the terminals on the filter was unwrap the connecting wires.  It
 was EASY. Great tool.

    Todd,

Good suggestion...even with space available for only one tool at a time it 
would be advantagous to preheat with the larger iron.  Thanks.
