mutron 3 ?

[zane]

Hello this is my first post so i hope it's in the right spot.

I was cleaning out my storage unit and found an old mutron someone gave me. I put batteries in it and it worked for about a minute then stated making white noise.

Can anyone tell me what the problem might be.

I am hoping it's not too bad since it will work when it is first cut on.
Thanks Zane
