Hi yes the TTS chips can be hard to find sometimes but they do come up from time to time at sensible prices too 👍 the speaker i use is 8ohm and is known as a sugar cube, ESU make them, you can also find them scattered accross Ebay 👍, il try and get the dimensions of them later 👍, thanks for watching 👍

@@ThisWayWorksTWW Yes, I've seen the sugar cube speakers being used and giving a better sound reproduction. I'll keep an eye on Ebay and see what turns up. Thanks again...👍
