[sdiy] Troubleshooting broken Waldorf Microwave XT

[Jonathan Lutz]

Thank you.. I will try the recommended steps.  I am still a little
wary on opening it up.  I think if it is not the PSU, I will just send
it out.

Do you think it would be killer expensive to repair if it is the CPU?  

Nice WAVE btw!!

JON
