Right Channel Seems Louder [NOT QUITE RESOLVED]

[oguinn]

Alright, new issue. I'm occasionally getting some slight static on the right channel. I plugged my iPhone directly into the SEX amp to make sure it wasn't the Quickie and the issue persists.

I flipped the amp over (shocking myself in the process because I was being careless - good time to remind everyone to observe proper safety protocol) and played music through some crappy headphones while prodding around with a wooden chopstick. There was no non-music noise while flipped over (except a light "wooshing" sound when the amp started, which I assume was the tube warming up).

The amp is in a corner with no wifi devices near it. I've been turning my phone to airplane mode (it's an iPhone, so I was sure to turn off all the radios) and just playing downloaded music. I don't think it's a wifi or cellular noise.

Is it the case that tubes will sometimes make some staticky noises during burn-in? Anything else I should try?

They can indeed make some noise until the cathodes form and the getter wakes up. It's usually best to reserve judgment on a tube until it has maybe 50 hours of play time. You could try cleaning the pins.

Makes sense. Thanks!
