So I got a bargain where the ad listed a MTH Railking Turbine Loco with PS2 that "doesn't run".
Having purchased lots of PS1 stuff that "doesn't run" for a bargain, and subsequently making it run with very inexpensive fixes or changes, I thought I'd take another stab at 2.0. The worst case was if I couldn't get it to work, I would just pull the guts and turn it into another PS1.0 since I have afew more spare bards. (and I only do conventional).
So here's the interesting part...Pretty sure I have 30-4060-0 tender with LocoSound from the Bantam line (says LocoSound on the sticker on the bottom and tender indeed looks to be LocoSound from the internals, just a speaker and a volume pot and a lump of metal.) But I have confirmed the loco is indeed a PS2.0 turbine (I'm thinking 30-1395-1). The tether is the same and the tenders look virtually identical, so I'm guessing whoever owned it plugged the wrong tender into the loco and couldn't get anything to happen so they called it broken and moved on.
The board looks to be in pretty good shape, the offending capacitor from my previous experiments does not look bulged or blown out in any way, and when I applied track power briefly the smoke unit made noise, so I know I'm at least getting electricity to that point of the board. So my question is...if I buy a battery / BCR cell (this is a 5V board) and mount it in the loco, can I still use the LocoSounds tender? I can probably trace the tether to the conenctions at the speakers and the volume pot and swap the leads at the loco board if I have to (although maybe MTH actually made the speaker / pot leads on the same pins as the 2.0? A guy can hope, it's the same tether plug after all...).
Is there anything that would prevent this? Was there anything else in the PS2 tender that the LocoSounds tender didn't have? Best I cna tell, it's only the battery.
