You must be talking about Majestic 9P6? As long as your power transformer is ok the supply should have 4 filter capacitors replaced. The cost of these parts will only be a few dollars. It may not be worth repairing if the power transformer is bad. A replacement could cost $50 or more.
It may look scary but most are not hard to repair.
