Hi Gang,

Got a TTS 37 decoder currently hooked up to a controller and the sounds are excellent. With trepidation, I'm about to embark on trying to shoehorn it into the Farish 37 with a sugar cube speaker. My soldering skills are average at best....I am quite envious of those who have managed to do it so far and their efforts will spur me on to see if I can accomplish it without either frying the chip or the chassis!!!

Later,
Stu from EGDL.
A selection of my pictures, real & model ARE NOW to be found at...

I used the same thickness platicard for base and frame. Probably about 0.2. I think it sounds ok.

I found the chamber made little difference and with the others I have done I just stuck the speaker to some thin plasticard, which saved a bit of night and made no difference to the sound output.

Wondering about that.
I was looking at a similar speaker from a mobile yesterday (15x11x3.5, 8ohm, 1W) and the rear of the speaker seems to be sealed.  If it is sealed then a chamber would have little if any effect.

To be called pompous and arrogant - hell of a come down.
I tried so hard to be snobbish and haughty.
