I have just purchased a used FURUNO antenna and gearbox. I have not received
it yet. It was made in 2005 and has been used on a commercial ship. It is
probably safe to say heavily used, but the price was right and it is sold as
functioning well. I will, disassemble it, repaint and mechanically inspect
and repair as necessary, but my question is about the magnetron. Furuno
states the magnetron is rated for 2,000 to 3,000 hours. I have no
maintenance history, but is to safe to think that without recent
replacement, the magnetron is used up? Should I just replace the magnetron
as just a general service replacement? It is an RSB0074-0062 12KW.
Thanks in advance,
Steve
