Help for building CRACK with Speedball

[i luvmusic 2]

I think the noise is caused by something outside of the Crack.  Are there any other electrical devices near it?

  Yes there are some HP amps,DAC and a laptop.I moved the CRACK and plug it  away from any other electronics to see if still picking up some noise and it still noisy no changes,Could it be some kind of internal problem?The amp was dead quiet before i did the Cree diodes This recently occurs right after i installed the CREE DIODES.

Thanks!

Could one of your tubes be going bad?

I don't think if it is tube related because that is the first thing i did changed both tubes several  times.

Thanks!

Not to put too fine a point on it but if the noise started when you put the diodes in, take them out.

 Yeah i thought about re-installing the stock diodes but then i really like the  Cree sound.
I will be installing a new set of PCB and Cree Diodes to see if this will solve the noise issue(hopefully).I even tried to re- flow some of the Solder joints and this did not changed anything.


Thank You!

I've changed the Cree Diodes and PCB the noise is GONE.
