Anyone have issues with Cambridge 851N?

I am original owner of Cambridge 851N streamer DAC. After 3 years the right channel went out and I paid Panurgy (Cambridge repair partner) $600.00 to replace the main board. Now, three years later, it is our again. Has anyone had a similar problem with their 851N and was able to have the issue fixed by a local repair service where they just repaired the faulty component?
