Hmm... Interesting idea, but this is my first camelback. It's on the way as of Thursday. I'm not certain what I'm going to be doing with it yet. I may try to double my money by reselling it on Ebay,I may keep it, or I may rip out the sound system,adapt it to my LGB mogul,and then sell the rest for whatever I can get back out of it. It didn't cost me much more than the Piko 3220 digital sound system,and the more I think about it,the better it sounds. I did purchase the Piko 36221 analog sound system for my Piko 0-6-0 yesterday evening. I was thinking about buying the more expensive,better Piko 36220 system for it,but it's a cheap train,so I figured"Why spend the extra $70.00 on it?"I did take the time to disassemble the 0-6-0 earlier today to figure out where the wires are for the smoke generator,a Suethe 7,that works best between 11-16 volts,so I will be wiring it directly to power and the sound system,without installing the included voltage regulator that's in the sound kit. I've installed a Suethe 7 in 2 other trains without any issues, so I'm pretty certain that there will not be any problems with a direct hook up on this locomotive either.
