Chameleon Blackface 581 problem
« on: November 23, 2018, 09:50:41 AM »
Hi not certain if this topic has it's place in here but perhaps someone can direct me to a better place.


Problem description:

Once the preamp (Chameleon 581) is warm, it start making a few sparky white noise then it become louder, no signal can go through it. if i let it cool down and start it again it work for a while till the problem re-appear, once it's warm again. Does that make sense? the unit is not modded. I have a second unit that work great! What could be the problem?

anyone!

You should check the opamps on small boards. Besides, you have a working preamp,  so you can borrow small boards from it and narrow the problematic part.

Thanks man! I will do that, good idee ;-) I'm just trying it again after check screws, etc and it seem to be alright, even after a few hrs to  be turn on. Anyway can't wait to build my own Capi V28 and AML Ez1073pre, just order them last week.
