In case you missed it Tim, we at WDTV-5  had one of those for several 
years, and if it had to be unplugged from the wall everytime it caught 
fire, I would have binned it loooong before CBS did. Running 24/7 as a 
message service at the CBS affiliates, the average time to a room full 
of smoke burnup was around 8 or 9 months. Good thing CBS had a service 
contract, but I think the 3b2 must have cost them money.  The service 
guys did the absolute minimum to restore its heartbeat.  New cooling 
fan? Its running, no. Running at 10% of its normal speed wasn't a good 
excuse to replace it.
