thanks to everybody who replies to this email, Bob,Jeff, and alll the 
others. This was the fix. The problem was a high pitch squeel. The power 
supply all the voltages were low exept the input pin 3 to ic803. The kicker 
was that the pin 3 was getting 36 volts ac at pin 3 found c805,and c806 
leaky. and q802 was leaky e to c.
c805
C806
ic903
q802

Thank you
