Folks, I have a buddy who has a 10 year old pair of Dunalvy IVs. The basically stopped working and what does come through is so distorted, he can only conclude they are severely broken. Before he sells them as firewood, does anyone know of a good "old-timer" or repair center in the Bay Area who takes on projects such as this? He has no idea if they need drivers, wires, etc. but doesn't want to bury the body without someone knowledgable who can first pronounce them "dead", or perhaps amenable to repair (with a cost estimate for the repair work). Thanks in advance.
