Problem in MAC MC240


Dear experts,

Recently my 240 has a big problem. The last power tube has lighted up as bright as a bulb. I have interchanged the tubes, still at that position the problem happened. Even I changee another set, still problem at there. Can anyone tell me some possible reasons?

Thanks a mil!!!

MC240 is auto bias. Better have a tech to check out what's going on. You can try to measure the voltage ( be aware that is is deadly 450+ Volts )
