It may be OK but I would change the electrolytics. Dripping
is common but I wouldnt gamble the transformer !

We got in a Marantz 8B tube amp & McIntosh MX110 plus
a pair of speakers the size of a refrigerator. Blown fuse in amp.
The transformer had a huge chunk of wax under it so the
guy bought an Zenith Allegro wedge of all things. He told
us to junk the old system !!!!! The boss couldnt believe the
transformer was bad so put another fuse in. This fuse didnt
blow & has been running since about 1980. The boss did
promise I would get it when he died. His wife said good idea
& she knew what its worth. He is about 80 now. Any day now
I will have my dream stereo.
