Question about Audio Players & Recorders
I have a marshall jcm 2000 dsl 100 head that will not power either or both of my marshall 1960 cabs from the 4/8 ohm outputs. I did not have this problem until I connected the second cab to the 4ohm output, turned on the amp got a short blast of sound then only a sizzley tone that seemed to eminate from the head itself. I quickly switched off the power unplugged the second cab and switched the head and cab back to 8 ohms only to find the same problem. Now the only way to use the rig at all is form the separate 16ohm output driving a single cab, on the 16 ohm setting. What gives?
Since you are getting some output, the amp section is probably OK. There are circuits designed to handle thge difference impedence outputs. This should be a relatively simple repair for any shop that handles these units. If you don't have one local to you, let me know and I'll locate the service info and get you more specifics.
