Ear834 yet to power up, does that arrangement have a chance to at least work correctly? The layout’s (PCB’s) ground(0) is connected to the chassis through 10r resistor in parallel with 100nf cap to the top and the earth from the plug connected to the bottom of the chassis.
Now I’m thinking of pairing it with the best possible for me option for amplifier, maybe Skunkie’s 6SQ7/EL34?
