Ampsandsound - Stereo 15 SE Feedback Issue


Gorm

Recommended Posts

Hi guys,

 

A problem developed with my Ampsandsound Stereo 15 tonight. When I started it for the first time since last weekend, there was now a noticable feedback buzz instead of the usual dead silence. As i approached the unit, I discovered that the feedback became louder when I moved my hand towards the 12AX7 position. As I moved my hand back and fourth from the 12ax7 I could control the "volume" of the feedback. So, I powered down the unit and replaced it with another 12ax7. It also exhibited the same behavior. I don't believe this is any sort of ground issue, as it was perfect for nearly half a year before today.

 

Anyone have any ideas?

I haven't received yet, Ill get it on the bench and will find the culprit. 

Im my experience... 150+ amps or so, less than 10 have every had anything actually wrong with the amp... tubes tend to be the culprit. Either way Ill have her back to singing ASAP.
