OK, I tried power up. No tubes installed. Voltages looked ok, bridge rectifier got HOT, then transformer started to smell and get very warm. Bam! fuse blew. Now I have no resistance between the primary and secondaries. Blown transformer?
I am using the Edcor these are my connections:
Primary: blk/grn blk-white/ grn-white
15 volt -centertap-15 volt from transformer connected to AC in on board.
250 AC from transformer connected to 250 in on board
9 volt AC from transformer connected to AC in on bridge rectifier
DC out of rectifier connected to "from rectifier" on board
1 ohm 50 watt resistor connected off board fastened to chassis.
I don't see any blatant mistakes but there must be one!
Help!
