Hi Jim, That might be a good conversion project for a large (1000 watt) microwave oven transformer. Saw off the secondary winding & remove the shunts. Wind say... 10 turns of copper strap (or as many paralleled #12's as will fit) through the space vacated by the secondary and add perhaps 25 turns to the primary in the space freed up by the shunts to reduce the operating flux to a reasonable level. That should be close. Tweak the primary a few turns to bring it to voltage under load. 73 & Good morning, Marv WC6W http://wc6w.50webs.com/ -- "k7rdx" wrote: Looking for a filament transformer for an 8171...If anyone has one they will part with please reply off list...Thanks&73 Everyone..Jim.. _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps ________________________________________________________________________ Try Juno Platinum for Free!
