MWave occasionally made a heck of a "arcing" sound when heating and you could see arcing behind a panel which covers end of magnetron. It got worse so I took it apart. There is a 1/2" or so diam. cooper cap that is over the end of a swaged copper deal (again I think the business end of the magnetron). The cap has a bb size hole in the center BUT there is also a significant hole which has been burned or arced out.
Anyway, do I need a new cap (it MAY have been attached in some fashion,welded? or a new magnetron unit or could it be the transfromer? (I did some review of other posts here). BTW, great forum site! Thanks!
