I knew BT were tight, but that is just silly!

Anyway, you lot of Brits should all be out enjoying the sun, I'm only here 'cos I'm stuck at work

edit: rigadig, I would go with Rapid, the Farnell/CPC website drives me to distraction!

Thanks guys, i will conform with you about the types i am going to buy before I make the purchase, but I can't do that till i get home.

P.S. Pinkmouse, I would love to be outside in the sun, but unfortunately fate has conspired to put a thermo-fluid dynamics exam in my way tomorrow.

I see that the amp has the ability to seperate the preamp and power amp stages via what looks like a jumper cable. If there is a set of terminals marked "Pre Out" and "Power In" on the back that are coupled together you may want to try disconnecting them and connecting eg a CD player directly to the Power In terminals.

This will allow you to determine if the hum is coming from the power amp or preamp stage..
The driver section of the power amp uses the same regulated supply as the pre, so if the pre doesn't hun then, if caps, it would be PS, but if both hum, it could be all the caps.

Rigadig, the best thing you can do is to desolder one and take a picture of it for us to look at, as well as where it come from on the PCB. Also measuring the spacing between pins is a good idea.
