I am still hoping to find that lost 675 Schematic and Service Bulletin,which covers Alignment, Re-stringing and a wiring diagram. You never responded to my question about how far off the Station you were listening to, and that of where the pointer was on the dial. Is it possible that the tuning drum is installed backwards? This could cause a like problem to what you are describing. Also if the take-up rotating string shaft, usually set around 2-2 1/2 turns. is being fed from the wrong side, this too could cause a similar problem. The stringing diagram of this radio, while being fairly simple, can still be subject to mistakes.
Also, has anyone tampered with the twisted pair of wires from Pins 5 and 8 of the 6BA6. W/house used this pair of twisted wires (black if I remember correctly) on many of their Radio Sets. It acts as a capacitor. I am not certain however if it could cause the problem you are trying to correct. The capacitance can be adjusted by snipping away a portion of the twisted pair, Hopefully you do not need to resort to this particular action. Not all models have this twisted pair. So far I have not found the need to adjust length of these leads.. This I think is going to be a process of elimination as you move forward.
