The mains fuse will blow after 5-6 seconds of power on. I think I should recap it. Check resistors. What would...

    Hello everyone. I have a problem with my High/Low power switch on my 1990 JCM900 MKIII 2100. I decided to try out the Low power (50w) mode the other day and noticed that it seemed louder than the 100watt mode. I decided to measure the volume with a decibel meter. The meter I used was able to...

Unfortunately, you could hear that, because it just didn't sound as good as his slightly later work. I then got...
