Hi All

Have a great Century 21 I have repaired and rebuilt the PTO and working great except for the CW monitor stage of the LM 3900 , all else is working great, looks like a component is bad in that oscillator monitor ckt.
Any ideas before I take of front panel again to slide the Audio bd out ?????
