I was looking on this model to turn the smoke off in conventional mode. The switch is empty in the engine. There is no switch on the tender. 

Doesn't the smoke "POT" under the water hatch turn it off if its turned all the way down?

No pot under the water hatch on this. It was made before the opening hatches and smoke pots were a thing. 

It definitely is supposed be under the locomotive cab judging by the manual. Maybe try opening the engine to see if the switch is inside the engine.

I have the same locomotive, no switch in that hole.

So how would I turn the smoke off in conventional?

I don't hear anything rattling around. 

I have no idea, I never tried to run this in conventional.

It seems to me the only way to determine this is to open the engine to see if there is a switch. I am pretty sure all PS2 5v engines only had a switch for on and off settings while PS2 3v had a pot for better adjustment. I would say open it up and find out what happened to the switch.

All PS-2 have volume pot and either a switch or pot for smoke. It is always where the board is.  So if board in engine, smoke switch is in engine.  If board in tender, switch or pot in tender.  G

The Manual has the switch in the engine which as in my photo its empty and John has backed me up on this. There is no switch or pot on the tender for smoke, only for volume. 

Before you burst a blood vessel on this issue, look under the rear truck on the tender and you'll find the smoke switch.

Lol well that answers that. 

Sometimes manual have old pictures.  PS-1 always had smoke switch on engine, because the smoke was track power and in the engine.  RK PS-2 5V had boards in engine so smoke switch on engine.

But PR stuff had board in tender and that is were the switch would be. G

I looked for a PS/1 Atlantic on the MTH site, but one didn't come up.  However, there must have been one as I said before that had to be left-over from a previous model using the same casting.

Long ago I asked and never got a good answer, but if you look at PS-1 stuff for example, there are plenty of extra holes on some models that make it look like it would be PS-2 ready.  Maybe at some point generic inserts where being used for the casting and you wind up with slots and holes not used.

Again, the guidance I gave is from our training, and documentation.  The smoke switch location is always where the circuit board is for steam.  You run out of wires in the tether otherwise.  G

I wonder if this engine was originally designed to be a PS1 and sometime during development/production PS2 was born and they decided to upgrade it. 

I have the same model.  My box says ProtoSound.  The engine has stickers say PS2 and it was a PS2 5v board.  There is a space in the engine frame for a smoke switch, but the actual switch is on the tender.

I suspect that if there wasn't a PS/1 version that there was either a planned one, or the board was originally going to be in the locomotive.  A number of the 5V locomotives did have the board in the locomotive.  They seem to have standardized on the tender location for the boards by the time 3V boards came along.

I also ponder whether this had anything to do with lionel also.  I believe at one point a lot of Korean stuff for both manufacturers so some standardization of molds for switch sizes/locations etc...  G
