Hi All, 
While I was ordering the pots I decided to spend a little more on 
better quality so I bought the (Eco) green conductive polymer track 
ones.. they say these are lower noise, anyone any comment on this 
(just curious)? 
They fit the boards ok so shouldn't be a problem in that respect.
The only problem I had was that the knobs I ordered, 16mm soft touch 
(Rean P670 series) don't quite fit the perfectly round spindles of 
the Eco pots.
A quick reaming (oo err missus!) with a 5.5mm drill bit followed by a 
6mm bit solves the problem, all smiles again after initial 
annoyance! :-)
Hope this might be useful to someone!
Regards, 
Phil (waiting for the postie to bring the last few bits!)
