I recently bought back an SX822 that I had owned many years ago. John Haines has helped me repair the logic board, and I have decided to ditch the record/play electronics and install a tube playback electronics under the transport. John French relapped the heads and I now have a 1/2 track and 1/4 track head on the stack, with head switching in the playback unit. The transport makes a most satisfying "thwack" when it is put into play. Crown transports are built like tanks!
BTW, John Haines of Jemah Services is moving to Colorado in the next few weeks, and maybe getting out of the repair and parts business. He gave me his son's number in Indiana: 574-206-9080, and he may be a resource for Crown parts and repairs in the future.
