By all means have your dealer open the Mac up and replace the analog
board and power supply.  Don't accept anything less than a complete
replacement of those parts.  Is your Mac+ an upgrade?  Infoworld reported
this week that some upgraded machines have been smoking and a few hav
actually caught fire.  All of the machines involved were 512K Macs upgraded
to Mac+'s.  Apple has said that the problem is that dealers are doing the
upgrade improperly in some cases.  If yours is a new Mac+, there may be 
a batch of defective power supplies.  Many of the ones that have smoked
have damaged the analog board, sometimes the heat has been bad enough to
damage the main logic board and in a few rare cases, fire has destroyed the
machine.  If you bought a new Mac+ you may want to be sure that your
dealer has not ripped you off by selling you a used 512K Mac upgraded
to a plus because all of the problems have been with those Machines
to date.
