[Amps] AL80A question

[RoadRunner]

Hi all ...Ihave a dead AL80A... It is wired for 220 and has been sitting
idle and covered for almost a year now...I plugged it in the other nite and
fired it up but popped the 2 fuses....opened it up, cleaned it out with some
lite compressed air....popped them agn....now I have new fuses in but when I
turn it on I get nothing...no blown fuses... nothing...I checked the
interlock and that seems to be fine...not sure where to look from
here.....there is power to the amp....
Thanks...
