I have a Vision 1000 and had a cylinder (#3) take a jump in indicated EGT 
after 20/25min. of operation a flight back.  Every thing was fine with all jugs 
showing 1350, when #3 jumped to 1500/25.  I don't really think a cylinder can 
get that high as mine seem to stumble around 1425.  My thermocouplers are 
mounted 2" from the flange.  When I pulled power during the approach and things 
cooled off, the thermocoupler seemed to read normal along with the others.  A 
friend with a Berkut said he had a thermocoupler go bad and they will either read 
nothing, or go full scale to 1500.

Just passing that on, but I think someone mentioned an alternate source for 
the exhaust thermocouplers.  Any one know before I order one from Vision?

Thanks
TEC
