An image of the 2nd IF amplifier and the AGC amplifier. The output to the product detector is between the two amplifiers. The black long round objects are ferrite beads placed on Gate 2 of the MOSFETS. After this strip was built, it was determined that the ferrite beads were not needed. The LEDs are rectangular types at the bottom of the image. |
The transistor used here is a very obsolete 3N128. The AGC line is connected to the Gate, which is hanging in the air. It is difficult to see the connection to the gate lead. The two brown wires at the bottom of the image go to the S-Meter. The two PC mount pots adjust the S-Meter. |
