Hi All I have a Singer/Gertsch FM10C , sn 135 with a bad scope.
The Oscope is Singer model ODM 1 Sn492 I have traced my problem, (noise on scope trace) to the Vertical Amp Board The board in my ODM 1 is a 5-003204-005 Revision D My manual has the diagram of a 4-003204-008 Revision A3 Therein lies my problem Does anyone have the schematic for the 3204-005 rev d that they can scan into an email. You can identify the board by the lack of intergrated circuits. the 008revA3 has 2 IC's , 5 transistors and the 005revD has only transistors 8total. Thanks in advance Ralph, W7HSG

No S-meter involved. A 3 dB increase in signal can make the difference
between unreadable & readable.
