My Lgb Sumpter Valley Mallet With Massoth Pulsed Smoke Generator

A known problem Neil - especially at the point the element finally fails, which of course it will eventually do.
 
Massoth make a (nominally) 6V regulator unit..
Neil is right.. The pulsed smoke unit will draw too much power to use a function output.

I'm unsure of the detail but in principle to get the same heat into the element at 5V compared to, say, 20V you'd need four times the current. Especially on a high output smoke unit this could exceed a decoder's function output rating.

HI I used the 19 volt digital unit wired directly to the track and the loco has factory fitted MTS and sound. I fill using a syringe and use 6cc oer refill. I also used the Massoth tubes between the smoke outlet into the loco chimney. Prevents any spillage. The smoke unit fits quite neatly in the smoke box with a couple of small brackets to hold in place.

I see you have it running about 3 chuffs per driver revolution. Are you going to try to tune it to 4 chuffs per revolution?

A assume you are using auto chuff.

It is running at 2 chuffs per revolution and is off running off the factory installed wheel sensor.
I prefer 2 chuffs as I think that you can hear them better!
 
We have had a bit of debate recently re the 2 verces 4 chuffs. Typically a Garratt or Mallett would do more then synchronise to 4 as the units kind of bedded together. Thus for me 4 would work, but I guess would give a rather shorter Smoking Time.

Just a thought have you or anyone on the Forum thought about making your own Smoke Fluid? The following link gives some ideas:-

I have read in the past of people having great sucess with such mixtures.

A mallet will give you a distinct 4 chuffs per revolution from the "last" engine, since there is no direct exhaust from the first engine, the exhaust from the high pressure cylinders goes directly to power the low pressure cylinders, so all you hear is the exhaust from that single engine.

Now, a compound, or simpled mallet will allow exhaust from both engines at the same time. Clearly an articulated locomotive with 2 separate stacks would have 4 chuffs per revolution PER engine, so you would hear these 2 engines, typically going in and out of synchronization.

The newer technologies in sound allow 4 chuffs per revolution, but keeps them from "smearing" at higher speeds. Ordinary sound cards have a single sound that is looped over and over, but at higher speeds, the sound needs to be "shorter" to replicate the higher rpm. Only the QSI does this now, although custom sound files could do it on the Zimo, and I suspect others.

I hope I've explained this clearly. Oh, and I have read about people using lamp fluid with success and it is much cheaper, and then some others have had terrible results.

I'll buy the pre-packaged stuff for now, it has more "anti-clogging" effects on the smoke unit wicks.
