OT - need advice from electronic guru

Hi, Malc

I'd suggest you to scope the 100 Hz 22v PP ... and see if it really reaches < 1.2 v level ...

In the "possibility" NOT, I'd suggest you to place a stupid 24 v 5 w bulb ( truck parts ...) just past the rectifier bridge.

You certainly noted there were no capacitors except the smoothing 22 µF ... there's an excellent reason to that !!! ... Hope you've respected it .

Ah ... last thing ... I did not see any pic in this design ...

Forum error ??? LOL

Thanks for the reply,

I've found that by increasing the value of the resistor from 270K to 660K slows the Dapol loco, so I guess that if I use something in order of 1M it will do the trick.

Uhm.. maybe using a PIC to generate the 50 hz pulse would also work.. and then this post would be in the right forum
