Not in your region, but a plug for my area: I have the good fortune of having found a competent electronics repair guy who has worked on my Mark Levinson 390s, my Magnum Dynalab Etude, as well as other equipment.
Electro Tech Services in the Montrose area of Glendale CA. (He used to be in Pasadena.) Tel (626) 792-4145 (I hope he is unaffected by the wildfire.)
