Trouble getting started
#15

The tubes in this set are: 7A8, 14A7, 14B6, 50A5, 35Y4. All wiring/connections have been double checked. All voltages check out except for the grid voltage(pin3) on the 50A5. It should be 55vdc and it only shows about 32vdc. Once I check the tubes I should have an answer.

Thanks again,
Eric
