I have made a short wave receiver from a basic circuit I have in an old Dick Smith book (no. 2)
It is not working.
I am sure it is wired (soldered) correctly.
When I powered it up it went "click", and when I removed the battery it went "pffftzzz" and I'm sure I head talking at the same time - but only for a brief second.
I rechecked everything and found that a capacitor I had ordered was 470uF 10v, not 16v as required.
I got a replacement part and changed it but now it just goes "click". Nothing else.
The other thing is that 2 other capacitors are 10uF 16v, not 10v as described in the circuit.
I cannot seem to source the 10v ones.
I read somewhere that a higher voltage doesn't really matter.
Is this the case or do I need the 10v ones?
