Thank you Ian for this excellent article.

My friend is soon to purchase this turntable and I will draw his attention to this modification.

Hi Ken

But the way your volume seems a bit loud.

Alter CV161 to a value of 1, it will sound a lot better.

Hi Ken

Assuming the class 40 has a tts sound decoder in situ,

Reading the instructions in column 6, part 5 cv table 1,

You will see that CV151 and CV152 have a default value of 8

These control the motor parameters.

CV153 and CV154 also are an alternative set of motor control parameters with different default values

(See column 9 with the heading MOTOR CONTROL ALGORITHMS DESCRIPTION)

So programming on the main (Pom) set cv 150 to a value of 0 this will insure we are controlling the motor with cv's 151/152

Then change cv151 and cv152 to a value of 35 and see if that makes things better

Hi Simon

Those are the chaps.

Take out all three of them.

They are put in by the makers due to legislation on such things as tv interference, but dcc decoders.have this requirement built in.

Merry Christmas.

Another decoder not mentioned, and worth considering, is bachmanns 36-552 2 function with 8 pin plug.

This decoder is bachmanns original release, and in my view the better, due to it having CV19 for advanced consisting and a one amp output.
