Be sure and check the 33K 4 watt resistor coming off the cathodes of (pin 3) of the EL84s. If it goes open, it will definitely increase plate current.*

*It'll make the cathodes less positive (more negative), which makes the (G1) grids more positive with respect to cathodes. Ergo, higher plate current.
