Problem solved

A small word of thanks to Lindy Connectors who have, un-beckoned, sent me a box of connectors (alongside their catalogue, of course).  Standing out from the collection, that was gratefully received, was a set of connectors with springs at the ends to stop them fraying so badly and ending up in the bin. These will be my first long term test then.  I am bound to day Lindy are quietly doing a pretty good job these days, the Cromo IEMs were lovely as was the Bluetooth NFC speaker that is daily use at the younger end of my household.  The open backed HF110s were also a fantastic value for money package and my Lindy smoothed Power Supply is also in daily use.  So thank you Lindy.
