I need part specification for BITX40 capacitor C7. I know it is a 470 pF. Is it an NPO? what voltage rating?
This week past, I put together my BITX40. Observing very weak audio signal, I was following the receiver diagnostics video ( ) and found unexpected behavior when probing the band pass filter. I also found that I have a bad audio jack linking the headphone jack and the speaker (probably a overheating problem).
Anyway, I was re-soldering the BPF inductors (L1..L3). While there, I decided to resolder the capacitors (C1..C7) as well. C7 came off when soldering one end (the other end "broke" off, and the chip came off on the iron).
I've temporarily repaired with a pair of .22uF in parallel.
Thanks,
