So a bit before you play try switching the amp on and not playing for like 10 mins then after that it should be fine. Another thing may be that the valves may need replacing..... replacing them may bring a new life to the old amp if it hasnt been used in such a long time.

Yes I agree you have to change the valves on it possibly IF this doesn't work then it may be a circut problem...
