Chips

[tonybonneyba]

I have a MM Class 201 DCC & DCC Sound Ready, I also have a Hornby TTS Class 67 sound chip which has a speaker attached.... you see where this is going?

If one wanted to "plug in" the 67 sound chip to th 201 (which already has a speaker), how would one do this?

Thx in advance!

 

Side note: i'm not going to buy a MM CL201soundchip, its too dare at the moment for me....

Ah, but the TTS chip has built on speaker 

It would just be a matter of soldering the tts chip to the speaker. But the tts decoders are 8 pin so you’d need an adapter to fit it into the 21 pin socket. And then you would still lose some of the lighting functions.

Assuming it has the right number of pins you can plug in any sound chip in theory.

You’ll need to desolder the wired speaker too. Also be sure the onboard is 8ohm a super the TTS only work with 8ohm speakers.

Ahh, sounds easy enough. I don't mind lossing cab lights.... pointless for my shunting layout anyways.

Theres enough room in the 201 for the TTS speaker, maybe i should keep that one instead?

Just bear in mind you'll lose the cab lights and probably headlights at one end. From what I've read the TTS decoders only have 3 functions.

Yeah you could use the TTS speaker once it fits in the shell. The factory installed one isn't great anyway.
