Spent last night aligning the IF. The slug in the "IF diode coil" drug the coil around - bad for the contact wires. After it was fixed and set to max gain I have too much audio and the eye tube is closed almost everywhere on the band even at its minimum setting (the eye tube has a cal pot). On a short antenna it would be fine, but I am not inclined to settle for that. Going to recheck the values on the AVC, AGC and tapped vol pot today rather than detune, though reducing the gain in this stage probably does not affect sensitivity but does affect the indicator (eye tube) and the IF AGC. If I can get that stage to respond better, that would be the best result.

12-10-late

All resolved and the alignment is complete.
