Hold on a moment there. You removed the plate cap of the 6146 and operated the transmitter that way? If so, why? A screen-grid tube should NEVER be operated with screen voltage and no plate voltage, because doing so can easily result in excessive screen current and a useless tube in a short time. It would be more informative if you specified what those pins are - Triode #1 grid, Triode #2 plate, etc. But some are. And the rest can usually be calculated. The modulator sections of the DX-35 and DX-40 are similar, so it would be helpful to compare manuals. Have you traced out the wiring and circuitry and compared it to the schematic? If not, why not? Have you taken resistance readings and compared them to what the resistance should be? That's nice - but why do you keep telling us that? You get a tax deduction for all donations, right? But the person who buys what you sell doesn't get the deduction. So why do you keep mentioning it? You mention not donating to ARRL often. Why? Please explain what your donations to charity have to do with fixing old radios. Consider that if you really want to fix old radios, you need to work smarter, not harder.
