Hi Folks...
I have an pretty antique Chinese Match Box sized Radio which is based on majorly 2 Transistors BC548 and 495 with 3 resistors,4 ceramic disc capacitors,1no 33uF Electrolytic Capacitor,2 diodes,all mounted on a 3.5 cms x 1.6 cms small PCB,with a mono headphone jack
This radio works on a 1.5 Volt AA size battery
I am looking for an IFT COIL for this radio which broke accidentally
Its a 2 legged Small Vertical Ferrite Bead with very thin copper wire wound on it with several turns and the same was mounted on this PCB
I tried searching the same everywhere in my city,couldn't find it
Can any body suggest me any substitute part/coil or suggest me where I could find a Circuit Diagram of this particular radio.
For your kind reference I am enclosing some close snapshorts of the PCB Top and the Back view,the list of Parts used in this Radio and the overall Radio Body as it looks from Outside.
I request you'll to please have a look at the same and kindly advise me if you can figure out the approximate value of this small MW Inductor coil used in this mini Match Box Radio.I can then probably replace the same with small resistor type inductor and make these 2 radios working.
Any suggestion would be of a great help.
The Parts List for your reference is as below -
Resistors (All 1/4 watt)
R1 = 10 K
R2 = 680 ohm
R3 = 33 K
Capacitors
C1,C2,C3 = 0.01 uF ceramic disc
C4 = 470 pF ceramic disc
C5 = 33uH, 16V Electrolytic
Transistors
T1 = BC 548 B
T2 = 495 C
Diodes
D1,D2 = 4148 B
Miscellaneous Parts
MW Gang Condensor - 1
MW Antenna Coil - 1
Small Ferrite Rod for Antenna - 1
EP Socket mono - 1
1.5 V Battery Holder /Snapper - 1
MW IFT Coil Inductor with 2 legs - 1 (this is the one of which we need to find the Value of ...)
