Well if swapping around the main filter cans does not produce any changes , and seing as your tryied out already swapoing the 2 output transistors , then the only other place I can see you getting a + 27 volts from is if transistor Q4 is the one goingi leaky after 5 or so minutes.

Q4 is one of the ones in the heat sink on that 5033 board.

Also you should rig up a away to hook up another speaker to the amp or get a big 25 watt resistor in series with your amps speaker to stop harm coming to it!

27 volts applied to that speaker is equal hitting it with over 90 watts and if it's a original CTS driver it's not made to handle that much power!
