What was the original Zenith Fly? It'll start with an "S" - most of the Portholes used the Merit HVO-53, with some windings not used on some models.

Original flyback was Zenith S-16204. On your attachment it says replacement should be Merit HVO-53 (3). What does the "(3)" indicate? Assuming it is a reference to a footnote. What does the footnote say?

I cross referenced S-16204 to Merit HVO-11. When I got the part, the original paperwork was inside (got it from Moyer in PA). Below are two photos of that paperwork. Showing it is a HVO-11 and showing that it replaces S-16204 out of the 23G22 chassis. So not sure if one is wrong, or both are right, etc??? Interestingly, all the S-numbered Zenith flys on the HVO-11 paperwork cross to the HVO-53 on your paperwork.

Wonder if the HVO-11 was a no good replacement in these models and updated to the HVO-53 later??? Anyone have any insights?

Thx.

The (3) indicates that the installer should use the inclosed sheet for instructions. Merit apparently consolidated their flybacks for the PortHoles into one number, unlike Thordarson, who kept it between FLY 52 and 53.

With the Merit HVO-53, there are several sets of windings, and you use only the ones for your set.

Thordarson lists one flyback for your model number, and another flyback for the chassis:

For Chassis 23G22 (and 23G23), use a Fly 53 to replace a S-16204

For Model G2346R (and G2346RZ), use a Fly 52 to replace a S-16566

They show the early PH's as using the 52, and the later chassis using the 53.

Dunno why the discrepancy - anyone have a Zenith 23G22 parts list? Going by model is sketchy, it appears.

Cheers,

There is a parts list for the 23G22 chassis in the Zenith Manual I posted the link to earlier in this thread, isn't there? From the ETF site.

I have a HVO 11 in my 12 inch set and works perfect. The 11 fits under the chassis also. My 19 inch set its on top and it uses the 52 flyback they are very different.
