Super2000 i have no audio output on ssb am fm ok ?

I suggest check the microphone connector and cable first. Are they OK ?

Instructions

Connect one end of your coaxial cable to the output port on your SSB Transmitter. Connect the other end of the cable to the coaxial input port on your RF demodulator.

Connect one end of your 1/4 inch audio cable to the audio output port on your RF modulator. Connect the other end of the audio cable to the audio input jack on your amplifier.

Turn on your SSB transmitter, RF modulator and amplifier. Adjust your SSB transmitter modulation by adjusting the knob on your RF

Look for open resistors near by, if the 2SC1969 shorted it has taken out one or two parts, also check for open foils on the printed circuit, beyond this a circuit diagram is needed.

did you found the problem,mine has the sam problems...reception not very loud on ssb,am fm very good...

Adj VR1 next to VR2 they are in the center of the main motherboard. VR1 will allow you to adj the S meter in AM mode only.

That mod that magnum does really ups the sensitivity. so much thats is too much. If that model has a switch for the compressor turn it off. It will help 100% and make it sound decent not twangy and over modulated. Just the design of these newer exports are not like the old ones.

is it steady output on AM with no modulation swing. then change the Audio transistor. SSB should work. they feed straight through to rf final. if no modulation on either mode, then check the mic, audio ic preamp.

Symptom:Buzzing or motorboating sound in either the transmit or receive.
Problem: TR602 is oscillating
Cure: Replace C602 with a .01uF cap {Cap is located in the power supply board}.
RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.

With SSB you have to put audio on the carrier you cant just key the microphone and expect it to output a signal unless you talk into the microphone at the same time this is how SSB works.
So if you talk and the meter starts to move then its ok, if you talk or whistle and nothing moves then the circuit on the SSB side of the unit is faulty.

sounds like some loose solder joints. check power output with external meter to see if output is ok . i think youprobably have 2sc1969 finals init unles someone has changed them theyshould put about 25 watts if tuned correctly. also check the antenna a and antenna b switch to see if something has shorted across it inside cabinet.
