Eddie Current after warranty servcing

I have an ECBA which is no longer under warranty, but still under my name in EC's record. There's some problem with the power supply so I needed to send it in. I wrote to Eddie Current, someone replied over the e-mail, and helped me remotely to trouble-shoot the problem. The problem remained, so I asked to send in the unit and asked for charged servicing. But there's no reply anymore after that. It's my first product from a "boutique" audio equipment company. So is it a norm that they just stop servicing old units?

 

Hi Marvey, the last mail dated 10th Feb 2017. The unit is #47. I appreciate if Craig can get it fixed, it's such a great amp. Thanks!
