Please heed Mark's warning about the grid coupler capacitors. The "consequential damage" can be serious: the output valves and output transformer.
If you haven't already done so, please also check R37 and R38. These are the cathode resistors for the output valves. If they have gone low (below about 200 ohms) that will also cause excess current to be taken by the output valves.
