Help! Something is wrong with my Ringmod

So I was rearranging my board and I plugged in the factory supplied moog PS with a step down converter (we are 240v here and the standard plug is 110) and it was humming pretty loud, so I plugged in the aftermarket Aus PS (which I have been using for years now) and now the unit wont pass signal. This seems particularly odd because all of the lights still come on as per usual. I have also been using that step down converter with my m9 for the past year and it has worked fine.

I opened up the fooger and I can’t seen any black marks.

Any ideas?

(I know this is a pretty sucky first post, but I need help from the experts)

Never mind, just heard back from Moog Tech support. Will need to get it repaired by a local tech.

Thanks anyway folks
