Audible OT vibration/buzz

Post by Bergheim »

I'm using an OT from a Peavey Valveking 100. Lately I've been running the amp through an attenuator, and with the amp wide open and the attenuator at the lowest setting (about 24dB down) I realize I can actually hear what I'm playing directly off of the OT, just like listening close to a turntable pickup. It's gotta be vibration in the core or the windings. Is this normal and/or safe?

Yes, normal. We can also sometimes hear sound coming from the valves when the speaker is radically attenuated.

Okay thanks. Might as well be the output tubes then, as they sit right next to the OT.

Yes, that fully normal!
