Curing the PA-dead of older FT-817

From Harry OE6GC, He writes:
One of the old FT-817 Problems is the PA goes dead during storage with included Batteries. This should occure in fact of self oscillation of driver and PA at battery voltage less than 7,5V. Maybe this is true only for some older models.

See the Attached PDF file for a fix.
