ok, so I brought a new kit, I did two things differently.
1, - I reversed the resistors - ie the gold band at the beginning of the resistor, instead of the end (I’m sure this would make no difference!) - ie gold at the left instead of the right.
2, - I left LOTS of ‘leg’ on the capacitors and the transistors (I was afraid that I may have heat damaged them on my first attempt).
Results - I get a different noise. It is not like the ‘beeping’ experienced on my first kit, so something is better.
However, the noise, sounds like someone playing with the volume on a channel tuned to static, could possibly at a very long shot be described as similar to a steam engine, by a deaf person. The whistle, well, certainly not like a steam whistle.
I think this sounds nothing like a steam engine, and the variance is really poor. The whistle is nothing like a steam whistle.
For something that cost £8.00, you would be better off buying a children’s toy engine, and taking the electronics out of that.
If you have the same problems I did, I woudn’t bother buying a second kit.
This is a real shame. I really wish someone at velleman who had a 3 year old child waiting for sound effects for their model train tried this kit.
I’m looking forward to my trip back to maplins…
