Re: magnetrons as diodes

["Tesla list" <tesla@xxxxxxxxxx>]

Hi Jesse,
 
While, in principle, any tube can be used for rectification, the
magnetron is not appropriate for this purpose. There are dozens of vacuum
tube rectifiers of different types, some with PIV >10 KV and RMS
currents >1.5 Amp. IIRC the 866-A, and 3B28 are such  tubes. RCA
manual TT4 has rectifier circuits for single-, three-, four-, and even
six-phase supplies, and data sheets for many more. The 866As are about
$35/pair while the newer 3B28 can be found for about $10/each or
less.

Hi Everyone,

I havnt really posted anything on the list before but i have been reading it for a while,

I was just wondering if the magnetrons out of microwave ovens could be used as HV diodes, if you removed the magnets to stop microwave generation. and used the filament winding on a MOT for filament power.

If any on has tried this before i would love to know....i supose they would quickly overheat though?

I was thinking it would be a good alternative to HV silicone diodes in a voltage doubler circuit (for a dual MOT supply----it keeps blowing diodes),

Any comments much apreciated,
