Desoldering braid optional to fix mistakes. I also used a digital calipur to measure the position of the Band Trimmer screws, then drilled two small holea in the back cover to save removing the cover each time. Continuing on, the board is completed with the population of resistors.

Otherwise, the IC may not be soldered in the right orientation, or the switch may have been damaged. Medium sized flat-blade screwdriver to push the spring terminals into the casing.
Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted. April 25, at Then secure this with the other identical machine screw. Magnifying glass and light to read small component datasbeet and markings also optional.
Now, the screws need to be sorted and the dials installed. For tuning drilled the back for access to adj screws on tuning capacitor. First, obtain the smaller volume dial and check the indentation for the rectangular brass stud of the switch.
March 23, at 9: Remove the plastic protective film on the front tuning scale, if desired. Do not touch the antenna or you may be burnt! The AM rod antenna connections can be made by looping out the enamelled wire over the top of the PCB is best and tack soldering the ends to AM terminals.
Then solder each successive pin taking care not to short out adjacent pins. We start by first emptying all components into a plastic bowl so they can be sorted through.
But at least they did provide the jack. Filtering is achieved with the external components — mainly R-C filters.

I enjoyed a lot this kit. This really is a kit that looks almost store bought! Note the orientation, unbend the pins, insert and solder away. Another radio that is in tune to verify received stations also recommended, but not absolutely necessary.
There is also a jumper wire marked with a J — this can be made with a scrap electrolytic capacitor leg. After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit.

Two AA batteries to power the receiver. Secure the rear of the case to the front using three long tapping screws on the exposed holes, and a short tapping screw on the hole inside the battery compartment.
Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason. Lead the yellow wire to the ANT terminal and tack solder.

For this, stick the wire through the slot in the rear of the casing, and the screw hole end of the antenna through the slot. Repeat for finding a known station, but instead adjust datashret left brass screw — the higher one.
Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately. Satasheet this stage, we are ready to make the final connections and assemble the unit. Next, try to close the case hooking over the headphone out jack first, and then clipping in the tuning dial side.
