I changed LA-100's default opamp and I think it needs to be repaired

I changed LA-100's default opamp to opa2134
and It didn't work. so I changed back to default opamp.
It works well but I feel like its sound has changed.
It sounds like little murky and unclear

maybe I think.. its circuit had damaged
I think it needs to be repaired

Re: I changed LA-100's default opamp and I think it needs to be repaired

The power supply is a very fine tuned serial and parallel type, so if you change to another opamp, then you can get different result. Also the Supply is not short circuit proof.
You can check pin 4 and 8 on the opamp to see if they are -13V and +10V.
If not i think you need to send it for repair. Please use contact formula for this.
