Ok, got back to work on the Maggy and did some testing on the ferrite loopstick antenna. I took capacitance measurements of the tuning gang in parallel with the antenna after disconnecting everything around it. I took measurements at 550kz, 1 MHz, and 1.6 MHz on the dial assuming the dial is accurate. Then using some math, calculated what the inductance the antenna should be to resonate at these frequencies. What I found was the inductance calculated out to be approx. 435 micro-henries. When I measured the antenna, it turned out to be 475 micro-henries, so I am thinking we are in the ball park close enough considering the accuracy of the settings on the dial. This exonerates the primary of the antenna for me. I don't know what the secondary should be but I find it strange that the antenna would be defective being that the windings are only one layer, what could go wrong! So I retested all the components in the RF stage and nothing. I ended up experimenting with changing the bias voltages on the transistor by changing resistor values hoping to get more gain and viola, success! I don't know how good of a performer this unit was in the day but it now plays decently. Now onto the FM where I believe the oscillator is not running!
