Orion 2150sx

Is this amp worth trying to repair or is it a lost cause this is how i bought the amp guess i should have opend the bottom cover first..

Notice the inductor in front of the torriod its burnt and it needs all new power supply fets,outputs,regualtors,ect ect..

 

[timwebb]

id fix it...just need alot of work

With the exception of the inductor, the cost of the parts is likely to be less than $30. You could rewind the inductor. For testing, the inductor can be used as is.

I have another 1 of theese amps with a bad inductor also..

I am going to replace the fets and outputs since they are shorted..

The amps is using SMP60N06's Wondering whats a good replacement for them??


Also Wondering does anyone know what core and guage wire i need to make new inductors for the power supply?? Or how do i go about ordering it as far as how do i determine what core and guage wire i need?

 

[Perry Babin]

The cores may be reusable. Use a dial/digital caliper to measure the wire.

The 3205s will work in this amp.

 

[S Merlington]

The core on 1 of the amps is not re-usuable all the coating is burnt off...

Any ideas on how to figure out what core i need to buy??

Also the wire on theese is 3 or 4 strands twisted together and then wrapped around the core do i need to only measure 1 strand then twist 3 or 4 of them together when rewinding it?

 

[Perry Babin]

You can wrap the core with Kapton tape to insulate it.

I don't have a suggestion for the core. Something similar pulled from a junked Korean/Chinese amp may work.

Yes.

Do i need to switch the gate resistors to 47 ohms if i use the 3205's?

Or will the 10 ohm be fine?

 

[seankane]

Switch them to 47 ohm.

 

[Perry Babin]

The 10 ohm resistors will work. The 47 ohm will take a bit of the stress off of the drivers but I never replace the 10 ohm resistors in the older Orion amps if none have failed.

 

[S Merlington]

replaced all power supply fets , gate resistors, drivers in the power supply..

All of the outputs are removed right now...

Perry stated i could use the inductor in the amp for testing right now..


Amp draws excessive current when i hook the remote wire up..


Anyone have any ideas?

Try powering up the amp with the rectifiers removed from the PS. They may be shorted.

Also, remove the inductor and use a jumper wire in its place for testing.
