Capacitors
Capacitors, 0.022, 0.033 and a 0.047
These were bought at Moongazer Music, the 0.022 were a bit more expensive. It is of a better quality and should be better to use in audio circuits.
I chose to buy the other two since the price seamed right and the shipping cost would have been the same with or without them. They can all be of good use when experimenting with the electronic part.
Total cost: $2.65
Note: The shipping has been excluded and are instead counted together with the bridge, since these capacitors did not change the shipping cost.
