Audphile1 , my impression they have good technical support after warranty before I bought the SA 10 and the Ruby. My mistake I should have researched before I purchased their product.Yes it’s sad to leave me hanging and their prospective buyers.Leason learn. Hopefully i can find repair shop that Iam comfortable with.I got an approximate estimate between $800 to 1000.Its way out of my budget.maybe the parts is now rare why it cost that much.
