That's correct, you had to keep the 625 pushed in when you set the 405 control too.

Flywheel sync did not guarantee picture would be centred in the scan. Picture centre
magnets could be used on mono sets, but colour sets may have a horizontal shift.
The line oscillator in the 3000 was the same as used in the 1590 portable.
