@roxy54 Have you just asked for them to send it back? They aren't that exotic. Any qualified tube tech should be able to repair it.
^^^ +1. Exactly. Get your AI preamp back at least. Can you do this, even if you send them a prepaid ship label?
Audible illusions Slow customer service
Just had to post this, been contemplate-ing doing so,Contacted the company for a power supply- as they didn't have one, but they had an older unit that they would refurbish and sell me for a very nice price. Well they found a problem in the unit that they couldn't get it up and running.That was over 1 full year ago, still coming up with reasons for delay.Nice units id find someone trustworthy to send repairs to...
