OK, Prompted by a couple of posts in reply to my thread in DCC Sound, I'm going to detail here as best I can how I did the DCC Converstion.

Items Used were:

ESU Loksound Micro Burnt with Class 50 Project, supplied by South West Digital

2 x Graham Farish Class 50 Locos, 1 China Chassis, 1 Poole Chassis

2 pin micro plug, supplied by DCC Supplies

16 * 25 (The smallest rectangular size available either way) speaker - supplied with the ESU LSM

Tools Used:

Warding Files

Dremel Multitool

Wire Cutters/Strippers

Soldering Iron & Solder (Lead Free)

Method - Roughly!

Cut off plug supplied on the Loksound.

On the Poole Chassis strip the drive train out and the metal cross member above the removable fuel tank. It is this hole where the speaker is going to sit. Solder one side of the micro plug to the speaker and feed the plug / cable up into the chassis, and feed out the front of the loco between the body and bogie - you may have to shave a bit out of the centre of the buffer beam to make the whole thing now sit more happily.

On the China Chassis, install the decoder as detailed in Gareth's (Trains4u) guides for standard installation into a split chassis loco. Attach the other half of the plug onto the now bare speaker wire from the chip. Feed the micro connection again out of the body between the body and leading bogie, on the China body you will definitely have to file away the centre of the buffer beam to allow free movement of the bogie with the wire on top.

So finally, connect up the micro plug over the rapido connector, then link together the Rapido couplings, and away you go!

I hope this helps someone!
