Hi Doug.
Yeah, dimmers are noisy %£@$&*% !
My solution is simple...
...I won't have 'em in the house !!
I have been known to remove neons from things as well !!
Mmm...
It might be that one of the amps is 'digital' & the other 'analog'.
I'm such a vintage ol' dude, that I don't know much about these newish digital-amps.
But they are small, cheap & efficient, so seem to get thrown in a ton of stuff these days.
As I am now finding out.
You could just try 'screening' the cable between the MP3 player & amp-board.
Sometimes some Bacofoil(TM) wrapped around has a simple effect on things.
Just connect a bare 'drain wire' up inside the foil, from your audio-ground screw-terminal.
Cover in tape or heatshrink.
BINGO !

Si.

Interesting Herb. And the possibility of radio interference (if that's what it is) had never occurred to me before this episode. I'm relieved it's so minor in my case.

Hi Si. Thanks for the heads up. If it becomes an irritation I'll have a go at that. I reckon I'm even more vintage than you as I didn't realise that amps could be digital or analogue. To me they're just amps!

My amps make things smoke when too many cluster up in one place.

One thing about my 'economy' hi-tech parts is ...
... they aint arriving by rocket-ship !
Oh well, patience is a virtue & China-Post is CHEAP !!
A slow trickle of boards, bits & bobs is getting here though !
Doug ...
... you might be interested in this newly ordered item.
It allows the digital-amp output of the panel-mounted 'micro' MP3-player & also your 'bluetooth' one with 3W+3W amps built in ...
... to be connected to 'normal' analog line-level audio gear.
eg. the 'low pass filter' board, mentioned earlier.

Basically this unit is 2 transformers & a few other components, in a box, 1 transformer each for Left & Right stereo.
This cost me £1.19p inc. P&P on eBay & is on it's way here as we speak.

Si.

All extra info thanks Si and I'm eagerly awaiting news of what you do with it all - and the result of course!

Hi Doug 
I am of course, going to Post more on 'the plan' soon.
The plan is changing a bit though, as the various boards & parts are found.
This is really the R&D stage.
I thought I would start with this, before getting underway 'proper' like.
Otherwise it would all be one huge 'splurge' of info in Post No.1 !
OUCH !
It is great actually, that various Members have already expressed interest in >> THE REPLICANT <<
I have exchanged a TON of eMail recently, with Juergen (Toeffelholm), regarding his own 7/8ths loco & layout sound project.
One thing that has come up from this, is more of an investigation into 'Bluetooth' sound transmission.
I was wondering Doug, if you had got that Blutooth equipped MP3-player yet ?
I thought that it only RECEIVED Bluetooth.
But do you know if it TRANSMITS Bluetooth as well ?
It wasn't totally clear to me, reading the text from Hing Yong Pong Electronics precisely WHAT it did !
It did say it was very good value & would enhance my lifestyle though.
Do you feel your lifestyle has been enhanced by the Hing Yong Pong product ??

Si.

Sorry Si, I've not got round to it yet as I've been distracted building a Cripple Creek/Minera Mexicana type small Mallet on a Roco chassis.
As and when I do dive back into ambient sound I'll report on developments. Good luck with yours and do keep posting on it.
Juergen might want to add his five penneth on here as it's all good education.
