Diode Zener tester
I make a diode zener tester,I saw the circuit from Here .I do not found the N-Channel JFET transistor 2N 5363,and i put the N-Channel JFET transistor BF244A and work the same good.
| Here it is the electronic material,plastic box,transformer,pcb,, e.t.c | Here i open holes to plastic box,and to put some material,switch on-off,jacks,e.t.c | And here the same. | ||
 |
 |
 |
||
| Here the electronic material with soldering iron it is ready over to pcb . | And from the other side. | Here i put the pcb inside to plastic box . | ||
 |
 |
 |
||
| Another one view . | Here it is ready. | Here i put from down side 4 little sponge | ||
