Hi.
In the circuit above I'd strongly suspect you are running Class "A" Push-Pull. The quiescent current will be high. I'd be inclined to either go for Fixed bias or higher HT and increase the values of the cathode resistors to get the amp into class AB or even "B".
The 10K cathode follower resistors could be raised to say 15k which could give a little more drive.
An interesting project but make sure you feed the leccy meter with plenty of shillings and turn off the heating in the house.
Good luck.
