Recommended repair/service in Portland, Oregon?

I'd appreciate a recommendation for someone who can check the capacitors, resistors, transistors or whatever might be needed on a vintage Classe DR-9 (and for other service/adjustment needs).
Many thanks in advance,Keith
I would have said Echo Audio, but as of yesterday they shut down their service department while they prepare to move location and won’t be taking on any new work until mid June at the earliest ... how urgent is your need?
