Where to buy/find equivilant flyback xformer

[espian]

Hi,

I've been working to put a Tek 571 curve tracer back into working
order (no video). At this point the most likely culprit is the
flyback transformer. It is labeled as a AT2140/16 (I'm getting no HV
to suction cup) and preliminary testing is not turning up other
problems.

Tek only appears to sell the entire video assembly (tube, HV circuit,
cable harness, and I'm sure quite expensive). Where would be a good
place find this transformer? Searching online, I find mention of
several versions of the AT2140, but very few mention the /16 version.
Can anyone out there cross-ref this for me?

Thanks in advance.

Keith

The following site suggests that HR Diemen's HR42053 may be a
substitute:

Here is a schematic diagram:

The following site suggests that the original Philips (?) part numbers
may be ...

3111 1083 3830
3111 1083 4450
TMF2220

BTW, I would first subject your FBT to a "ring test".
