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.

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.

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.
