    My 897 won't power on. I know there is a kit you can buy to repair it. Where can I get info on repairing it in English and get the kit ? Bruce.

    There are several things that will prevent an 897 from powering up. The kit you are talking about is a collection of the typical parts that go bad. I have seen these on Ebay from time to time. I have repaired several of these. Using a low current power supply, voltmeter and the service manual, check to see if the un-switched 13v is present at the ribbon cable on the Main board. If it is not, trace the diodes and transistors on the PA board ( bottom side) that supply the un-switched 13 volts to the main board. If it is present, then check the "power on circuit" to see if it is switching with the power switch. If it is working trace back to the power on relay drive transistor. Let me know what you find.
