Hi all -
Was hoping to get some help on a DX-100 that I am helping to get back on line. We are making good progress, and So far seem to have good output, good modulation, and the audio sounds quite good on the monitoring receiver. All functions seem to be working, but have hit an odd problem. When I turn the meter switch to "Grid", the meter deflects to the left -- as like a negative reading.
For any experts on the rig -- is this something that might be obvious? I could probably figure it out EVENTUALLY -- but maybe someone could offer me a shortcut? Or at least some recommendations for places to begin looking...
Thanks in advance!
Jeff
Not much information regarding voltages present in the rig, or how much power and modulation percentage you are getting.
What is your 6146 screen voltage?
I would set the screen voltage to about 165 volts initially with the clamp tube adjustment pot. (500k ohms) until you get things sorted out and then set for about 175-180 Volts.
Have you tested either the 6146 or 6AQ5 tubes as yet?
