magnum s9 no tx need docs

[DT307]

magnum s9 9821r20
no tx output only slight rf getting to pa stage.

finals ,driver,predriver,pre-predriver all pulled and checked good tr56/43/44/45/46

wet finger on the balanced modulator pins (ic3) about 20w out or on the pre-pre driver 60w output

i think the issue is where the red wire comes from rear to a transistor on the front solder side next tied into the fm full power diode d506 as if i fit a diode i get 5w output on fm and am nothing on ssb (i can hear my self on a near by radio but not enough rf to drive the pa stage )

looking for a block diagram and a voltage chart so i can continue
(have contacted pallomar and no reply)

c122 also tested good and 8v feed to ic 3 (not the an612 i have on my diagrams but a standoff board with i guess an upgraded version )

Have you tried cbtricks?

 

[DT307]

yes thanks..nothing what i need i guess no 1 has them as Eric did mail me back and said all he has is on cb tricks ......find it odd the people that make them dont have a voltage chart or a block diagram. oh well old school bit by bit it has to be then

Well, does it have that "TP 6 TP7 TP8" stuff - how's that doing - do you get any voltages?

You know, AM Regulator stuff...

You can always post a pic of your board and if it's the older S9 series - I believe they use a Galaxy equivalent board layout - should be pretty simple for others to recognize and help you out...
