Sounds as though you have a direct short in Primary Amplifier circuit. Have you dissasembled unit and ohmed out Transformer? Also Cooling fans that are high amperage draw that short out as well as you said Bad Capacitors. Try ESR meter on Caps.

Sounds like you have lost the thing that does the amplifaction. Look inside see if you can see something perhaps on an heatsink, I think it will have gone, but it's just a hunch!

SOURCE: Acoustic Image Contra series II - No audio passing

I decided that without a schematic and parts list I shouldn't even attempt to repair it. I had taken the cover off and disconnected the control board from the amp. When putting it back together to return to owner, I noticed the plug and socket for the control board did not go together properly. After a little maneuvering, I managed to get then joined, and just like that the amp was working again. I suspect that who ever had repaired the ground on the guitar had opened the amp up as well, and just didn't get it back together properly. The amp wasn't really damaged, after all.

SOURCE: need a schematic for a Samson Servo 300

Apparently Hartke and Samson are one and the same. See if possibly this link might be close to your unit. It is for an S500.

My velodyne subwoofer is making "clicking" sounds and is not producing normal sound (e.g. music). What may be the problem?


You did not state what model this is.

If it is a servo controled unit, you may have a problem in the control circuit.

The models that use the servo control stystems should only be serviced by Velodyne or one of the listed service centers.

Velodyne is the only source for parts for these units.

Woofer,s outer ring is ripped.


To fix this problem, you will need to contact Velodyne.
They may be able to replace the surround or recone this driver.

Because this system has the "servo" control, you need to have the accelerometer conected to the amplifier. With out it, the amplifier will not operate.
