I'm a little confused here:The Ts2 has got better sounds and more control features the than the '1', the lack of those bulky capacitors makes for easier fitting, although as replacements in Genesis locos where they hang over the flywheels, not a consideration. I always thought the '1's had pretty good sound and enough lighting controls for most applications.
The Ts2 and the Eco in board replacement types, both have the advantage over the '1' of 2amp motor load and 2watts of speaker power availability.
Oddly, the shrink wrapped decoders in the new range are still only 1amp and 1watt.
1) Did the Ts1's all have bulky capacitors?
2) Did the Ts1 all have a 1 amp limit,...and the Ts2 have a greater amp rating?
3) Are there Ts2 in skrink wrapping?
