If your tubes light, the fuse and thermistor are fine. If the tubes light and do not self destruct, you either are missing the high voltage supply, or something else common to both channels (other than the bias supply) is wrong. Check the mono/twin amp/stereo switch (not that it's the only possible cause) if you have both 435 volts and 140 volts from the HV supply.
MC240 HELP PLEASE
Ive had a mc 240 for years, its never been a problem child, loud but never a problem.
I recently brought a 2nd one to drive my mids and tweeters.
I was useing the amp the other night,and it made some clicking/on/off type noise's near the 117/125 volt switch and then near or in the the tranformers,then it just went silent.No sparks, no smoke, no shock,just silence.And thats the way it stayed ever since just bloody silent.(now this one has become a problem child.Was useing cd player into c28 into mc240 in evo 40 speakers at the time
Ive checked the cd player the preamp the speakers with a second amp they are all fine.Tubes still light up, fuse seems to ok.
The amp had just been serviced before I brought it had new caps and more,the guy I brought it of on audiogon is 100% reliable and if he says it was serviced and caps replaced then it was .
Anyone got any ideas on what the problem might be.Bye Paulie.
Thank you to all that reply .
