Pith, I take the simple approach for testing coils. Check the schematic and the coil base. In some cases the coil also goes out the top to a grid cap. Hook the meter on the grid cap and check underneath to make certain you have a low resistance reading on at least one of the terminals. I then mark that terminal or terminals with a black sharpie. That will leave some other terminals underneath. Clip your meter on one of them and check the others, need low resistance between others. Black mark those. You should end up with them all marked as having low resistance to one or the other.
Perhaps if all check out well when you did the rewind you might have reversed the wiring on that winding. If you have good resistance you may want to try to move the wires going into the coil and reverse them.
Hang in there. Jerry

Thank you Gary. Hi Morzh. These radios are 6 transistor radios. Sadly no tubes. Thanks though.R3Sons — 02:19 PM |
