Sounds like a serious case of microphonics to me. The bad part is that the tubes are soldered in place. I don't understand why MF continues to solder tubes into their tubed components when most manufacturers use sockets. For the convenience of the end user, they need to be using sockets to make replacement of tubes a simple thing.
MF A5 is messed up
I turned it on and all that is coming out of the speakers is a terrible screaching sound. I have had bad tubes in components before(never a cd play though), but I do not remember a sound such as this. Could it be just a bad tube? Any iput or suggestions would be appreciated. Thanks
