Cheers much appreciated! shall make my decision on which to go with today.
the other thing is line-out i would like to add one, would there be a proper way to do that with the B1 ?
my friend wants to feed a line out to a different amp so that he can chose which amp or even both the music from say CD player is played on.

Thanks Mark for the radioshack recommendation ,looks good yes i think ill be able to suss out how to wire the Potentiometer with a bit of time.

Having real trouble finding Dual Gang 25k Potentiometer at 0.25"

This is the closest Iv'e found and its 47k not even ebay has them in this size
27ESB473MMF50NF - TE CONNECTIVITY / CITEC - POTENTIOMETER, D/GANG LOG 47K | Farnell United Kingdom

Is there a way i can modify to work with a lower or higher than 25k pot ? i think if i was clever i could calculate series/parallel resistor to add lol

The selector switch im happy with and think this cost is worth it as i think its well built!

Is there a 20k or 22k pot that is within your budget?

At a push you could use 10k, if your sources can drive that Zin?

Rixsta, the B1 will work with higher K pots. it.s just that 25K is the recommended one. Yes I found they are a little difficult to get and have settled on 2 mono 25K 24 Step Ladder Type Mono Volume Control Attenuator (item No310603383314) from Ebay @ US$26. They also do a stereo pot but I still like to have some balance control over my system.

What kind of strain relief is this on the power cord of Nelson's B1?
