Here is part two of the Graymark short wave radio. I've now found where the original builder installed a 47Kohm resistor where there should have been a 4.7Kohm resistor and a 4.7Kohm resistor where there should have been a 47Kohm resistor. This thing was built so carelessly that I think it would be easier to take it apart and start over.
