Time for more voltage measurements. Does your tuner match that of the sams folder you've been using, a single 6AG5 and 6J6? If so verify that your DC pin voltages match what Sams call out for V1 and V2, from the voltage chart on page 8.

For anyone following here's the tuner portion of the Sams 101-5 schematic along with the voltage chart.
