Title: Hum left channel but goes away after 20 seconds?
Post by: Jimb0 on June 10, 2018, 11:28:09 AM

Hi. I've been getting a slight hum on the left channel of my headphones after I turn on my Crackatwoa. Is this normal? It goes away after about 20 seconds.

It's not abnormal for a tube to make some noise as it's warming up.
