a real challange?

If coil #xx1 was ##mm on the left side with the leads, and ##mm on the right, sitting ##mm above the metal chassis, does the replacement have to be exact, or is there some wiggle room?

I was screwing around with my 328, and it's pretty accurate with capacitors, ESR, and even inductors over 10uh are close enough. What it's not accurate at is resistance under one ohm. A 0.47 read 0.33. On my Fluke, it read 0.46.

Any component in the IF should be replaced as close to its original physical location as is possible. Even moving a part aside to resolder a tube socket has some (possibly insignificant) effect on alignment. In any case, you don't want to leave long leads.
