Hello...

I am curious regarding your experiences with microphony effects with 300b tubes.

At the moment I am using the normal EH 300bs and one of them really acts as a microphone. One can hear through the speakers if somebody is touching the Kaiju chassis or turning the volume up or down.

The effect reduces a bit when the amp gets warmer but is still there after two hours of listening.

Any recommendations regarding tuning parts for dampening microphony on 300bs?

Input would be very much appreciated.

Thank you so much and have a great sunday,

Chris the swiss...;o)
