New to Forum- 47-1230 is my 1st Restoration
#21

Ok so I got the transformer sorted out, it appears to be ok based on voltage and I got everything identified. Per Radioroslyn, the black wires were NOT the primary wires, the white wires were and they ohm'd out at 4 ohms. The yellow wires are the high voltage wires with a green bias wire, the ohms were only 110 between the two and 53 and 58 ohms between each and the green bias. The schematic shows it is supposed to be 260 ohms between the two yellow wires. The red wires ohm'd out at .8 between them and .6 between each and the brown bias wire. The blue wires ohm'd out at .4 and the black pair at .4 as well.

Under the voltage test, using the WHITE primary wires Icon_smile there was no amp draw obviously because it's on the bench and at 115 VAC I had 6.6 VAC on the black pair, 5 VAC on the blue pair, 6.5 VAC on the red pair and 680 VAC on the yellow pair. Based on the voltage output it would appear the transformer is performing correctly? I do not understand why the high voltage pair only ohm at 110 when the schematic shows them at 260 ohm's. What are the groups thoughts on this?
