loaded question, Depends on the chassis and the flyback, it should be somewhat close to what it says in the sams, within reason.
but it will be drastically different from TV to TV, year to year. this is not unusual.

Because I’m looking back on the nos flyback for the Motorola sams says 600 ohms but the nos flyback tests at 470 ohms and I put the old one back in because the hv wouldn’t go above 19 kv but in the end I was thinking it had a short or something was loading the power supply down when afterall it was no activity in the IF since that was fixed the hv came right up so I’m assuming the flyback is good afterall . aftermarket flyback would not be perfect and exact as the original flyback.

Resistance doesn't drop without a short. If you have a short it WILL show up on a ring test, and it will noticably effect HV if not outright kill it.

I never checked this flyback from the beginning so maybe it was made this way I don’t know. I guess what I’m asking is the 470ohms that this flyback measures is it to low to produce hv if of course it was made this way and not shorted in any way.
