McIntosh MR78 tuner repair

The glass on my tuner needs to be cleaned on the inside. I'm asking those who have opened theirs up if it was a difficult job or not. I am fairly handy and was wondering what is involved. Or should I leave this up to the pros?

Ralph, thanks for your good recommendations. Actually just dusty on the inside of the glass. Not sure about the filter capacitors but I'll take a look while I'm in there. No noise while tuning but probably wouldn't hurt to Deoxit the bearings also while I'm in there.

How I can tell the difference between an original filter cap and a replacement?
I've owned the unit some 6-7 years and don't know if the previous owner(s) had any service work done on it.
