[QUOTE="Craig Hauber, post: 106455, member: 272"] Re: Amp kicks out on Mic ONLY with 8 ohm to 70 V Xfmr on Amp output Those crappy "Sherwood" receivers can barely tolerate 4-ohm stereo loads. A local jukebox vendor was using them for extension speakers and just about all of them have been replaced by me with "real" gear. They would go into protect mode with a good heavy bass note at not full volume levels -and their protect method was simply powering-off so the barkeep would always have to run to back room to turn it back on. After a few weeks of this they would usually fail permanently. I simply can't imagine one putting up with the abuse the OP is describing -especially after JR's posted reply. I also can't believe this thread has gone to 22 posts without even minor chastisement and some recommended replacements. (even the cheapo ubiquitous Pyramid 100w "PA amp" you find in the back of VFW and moose halls nationwide costs about the same, can outperform it by a long shot and last through decades of abuse -and interestingly enough I think it still comes with a real mono "phono" input :-) [/QUOTE]
