I've worked on a few of these and found a lot of the red hunts coupling caps to be very leaky as well as several of the higher value carbon resistors had gone high. Check the usual voltages around the valves, IE cathode, pins 3/8 on the ECC valves should be around 1v, grids should be 0v. Clean the pots too.
