I had this gone through and had all the power supply caps etc replaced along with a battery mod and a debounce circuit put in so..no data skipping. The rack ear supports are missing and I bought it that way. One of the rack ears has a tiny crack at the top and why people don't reinstall the supports instead of losing them I'll never know ?..Anyways..It's all freshly tuned up and will last another 20 years!! $950.00 shipped
