Magna vibe power squeak

[adam_bz]

, I'm putting a nagnor vibe together. It a got a squeak which is coming from the power I think. It's squeaking in time with the led pulsing.

Any ideas how to get rid?

Power it with a battery. Does it still make the noise? If it does, it's not the power. If it does, then increase the power filtering.

There's not much in this circuit and even less you can do to correct any shortcomings in it, unfortunately,

Thanks for getting back to me.  a 100r between the socket and 9v sorted the squeak!
