Mk 134

I have tried for many hours to try to get my MK134 Steam Engine Sound Generator to work with no success- absolutely no output. Can I send the kit for checking?

Yes, you can.
You can find the address on the packaging.
One final attempt: if you provide hi-res and sharp pictures of both sides of the board, we can take a look at it.
Post links to the pics, as the forum does not allow pics.
