Hello,
for a friend I replaced the standard fx decoder of the Ludmilla with the Hobby mSD sound decoder set. The mtc21 adapter bord is ready to connect a buffer capacitor which is very usefull for this loco. There is plenty of space inside the loco. I decided to use a 1.200µF capacitor and glued it directly under the roof.

I realized, that the distance of the two connectors is the same like the distance between three connectors of the pin connectors, I bought in the past. Therefore, it is very easy: Just cut the connectors of the capacitor in the correct length and prepare a connector on the cables. Now You can plug the connector directly onto the capacitor.



As always, I used the standard charging circuit, which is fitted into the black shrinking hose:



The loco drives very smooth and without stutter on my test M-rail.

Next, I will test the Doehner&Haass SD21A-4 Sound decoder with the Ludmilla sound from Matthias Henning in this loco. I will create a video with this sound project. Stay tuned!

Yes, it is confused!



1000µF is as good as 1200µF, or better if there is enough space available, 2200µF or 1800µF.

Important, it should be at least 25V versions, better 35V!

???

There is only one value given:



And, yes, we use in germany often a wrong notation.

For technical values, You can read 1.2µF or e.g. 15.2mH. But, it is not misunderstandable, because:

If You want to say 1200€ then You could say 1.200€ or 1.2k€ (correct euopean notation would be 1,2k€). But 1.2€ is never a short form of 1,2k€!

Or, in general notation:

1,000,000.00 (US, UK)
1.000.000,00 (European)
1.000.000.00 (wrong European, mix of US and European notation)

But what about the Doehler&Haass Ludmilla sound?

Yes, I will spend a bit more time for fine tuning, but the speed in FS1 is really very slow. You can see in the middle of the video.


It is a common way to shorten a value bigger then 1000 with the short cut "k":

1000 m/h = 1km/h
1000 € = 1k€

Many people think, that "k" is a short cut for kilogramm, but that's wrong. "k" says "* 1000". When You are told to buy 1k apples, You should buy 1000 apples, not only 1kg!

In business areas it is avery common to use k or M for thousand or million:

10k€
50M€

You may have a look into the balance sheet of big companies, You will find it there. I use it therefore also very often, because our calculations are done in k€, too.

Hello,
the sound volume is adjustable for each sound slot seperately. You can do this by POM, so it's very comfortable to adjust and test until it fits Your needs.
