Hello all.
Finally got round to spending some time on the TTS 37 and have ended up fitting a bass reflex enclosure @8ohm in addition to the standard speaker.
I`ve sealed the factory fitted speaker,as noted it is a little too big to fit into the recess.
Overall the loco does sound better,but I may even remove the Hornby speaker,cant decide at the moment.
Some added weight,etched roof fan,new window surrounds,buffer beam detailing etc and weathered,the loco will be looking good.
Personally I think these locos are a good buy,some would probably say the models are rubbish compared to more recent models,BUT,look at a super detailed LIMA class 37......
Cheers all....
