Hey Rich
Thanks for your advice, thanks to all that have wellcomed and offered advice.
I started with all the real basic tests and moved to checking the fuses which were fine.
Made my lovely wife buy some contact cleaner in her lunch break. Quick spray in the balance slider area and gained a little sound on the right hand side ! yeah !!
pushin up the volume to max gained some more , yeah ! yeah !!!!!
I've left the unit running on max (headphones in) for a couple of hours now and seem to have a perfect system . I'm very very pleased as I love the design and feel of the amp.
I wonder if it will need to be warmed up before use everytime ?
Off to play some led zep !!!!!!!!!
