Battery Pack dying?
« on: 15 Mar 2017, 08:41 pm »
Hi All, just a little question, with the battery pack powering my Sensation, l m getting a high pitched, throbbing noise, that sounds a lot like John Bonham's bass drum pedal on Led Zeppelin's ' Since I've been loving you' ( that is audible close up to the speaker), this does not happen when my JT Dynamic PSU is in use..... so battery PSU on the slide, as it is quite old now........

Thanks for looking.
