I love this amp. Twice today my GM36 "Store" LED came on without being touched and the amp went quiet. Pushing switches and making adjustments had no impact on this condition. shutting the amp off and on brought it back to life. I use this amp frequently for shows and am concerned that I may be headed for reliability issue.
The amp also has recently been shutting the output off and lighting the speaker kill switch once or twice per show. Pressing the speaker kill switch does not bring the audio back. Again shutting the amp off and on restores operation. It did this about a year ago and I replaced the EL84s. It worked fine for quite a while before starting to do this again. So I replaced the EL84s yesterday (Apex matched quad) and now when testing it before our next show this "Store" LED issue pops up.
Anyone have a similar experience? Any thoughts on a cause or what this indicates? And more importantly is there a solution that I might perform myself? I know which end of the soldering iron not to grab.
Thanks,
Pat
