Haha, thanks, newbee. Cheap is good. I wouldn't call your fixes unsmart. The amp is heavy, as you know. I won't move it unnecessarily.
Btw, where did you get the gold plated tubes?
Rogue Audio Cronus Magnum III crackling static in left channel
This has been going on almost as long as I've owned the amp, 5 years. I bought it new in 2021, so it's 2 years out of warranty, so no help coming from manufacturer.
I can stop and or aggravate crackling by wiggling the tip of the left 12AX7, less so by touching the left 12AU7. I've transposed the two AX7s and it helps temporarily. I don't suspect the AQ Evergreen cable or its connection to the DAC.
I've tried switching inputs to Aux 1, Aux 2 and CD, but the noise occurs in all three.
Any thoughts, suggestions welcome.
