I called the service center this afternoon and the tone control board arrived on Friday! The tech has installed it and will have testing complete soon. It may be ready for pickup Friday, Monday for sure. I can hardly wait. The stereo has been packed up and out of commission for 2 months. The rack has been loaded in the new place for 2 weeks and I'm ready to Deoxit the hell out of everything and connect it all up. I think a little Jeff Beck Performing This Week: Live at Ronnie Scott's Jazz Club will be the test CD for my sound check. The neighbors won't know what hit 'em.
