Default help:schematics for a Denon SA-3350 int amp

help!..just a newbie

i just bought this vintage Denon Sa-3350 int amp dirt cheap...i cleaned the insides, sprayed contact cleaners on the pots and recapped the power filter caps...i was test running it for about a 2 hours when i smelled something like a burnt rubber, i opened it up and the power transformer was kind of hot...turned it off...let it cool a little bit, i tried turning it back on..no dice...now no more power...there's no busted fuses, no burnt resistors...

hello.
can you measure the resistance of the primary windings of the transformer (with a dmm) ?
