IF amplifier with a crystal filter circuit
The IF amplifier shown in the figure is based on the design of popular MC-1350P IC. The chip can be gotten by mail from the accessory store or from the smaller stores. This chip is basically the deformation of LM-1490 type and LM-1590 type circuits, but it is easier to use. If MC-135OP components are not easy to find, the exactly same chip can be found in the online service instead, such as ECG or NTE. These series of components can be bought in the local electronic parts dealers, which are for service and repair shops use. The performance of using MC-1350P chip is identical to that of NTE-746 chip (as well as ECG-746).
