osc xfer rewound backwards
#1

i replaced the corroded secondary wire on an oscillator transformer but wound it backwards. didn't work. AT ALL. i'd like to know why.
by way of context, the transformer is in a 1938 philco auto radio, model no. F-1540(Ford).  part no. 32-2828  the transformer is similar to the IF and oscillating transformers in all the 6-volt ford radios from the 30s that i've seen. i did get some reception by reversing the leads to the secondary coil [wound backwards]. too late now, but i didn't experiment with the primary leads reversed.
don't ask how long it took me to discover my [rookie] mistake.
