Message-ID: <1556@saturn.ucsc.edu> Date: 7 Jan 88 06:57:57 GMT Sender: usenet@saturn.ucsc.edu Reply-To: haynes@ucscc.UCSC.EDU (Jim Haynes) Organization: California State Home for the Weird Lines: 10 References: Just wondering if anyone understands the innards of microwave ovens. The only magnetrons I'm familiar with are the World War II radar things that have a cathode that takes minutes to heat up and that run 20 kilovolts or so between cathode and anode. So how do the ones in ovens get instant-on, and what kind of voltage to they need? The units don't seem heavy enough to have a big transformer in there. haynes@ucscc.ucsc.edu haynes@ucscc.bitnet ..ucbvax!ucscc!haynes
