Hi guys, Marcelo here from Argentina.
I currently own four AG4700's. 3 in working order and one for parts.
First let me say that there are two versions of the AG4700's:
The first model is the most known has a front panel the look like this:
a little more detail:
And then you have the second model, or like I called: "the M2 model" (or just Model 2):
As you can see there are less buttons, a new switch and some new indicators.
Less buttons:

and the extra switch:
And the panel:
If anyone had some experience with these, please let me know. I still haven't found a way to turn the M1 and M2 indicadors or even what it does.
Anyway, this thread it's about heads.
Finally, after months and months of waiting, a friend o mine sold me his AG4700, wich is the "M2" model I mentioned.
When inspecting this AG4700 the video head is different from any other AG4700 I have.
Heres' a pic:
As you can see, this head is a VEH0651, wich is the SAME used in the HS1000 (according to the Service Manual)!
Also, the AG4700 (and all the other AG4700 I have) uses the VXP1747.
Like these:
HOWEVER.
I found in this site a post by
dcmatt (
Panasonic NV-HS1000 video is jumping?)
And there you can see his HS1000 head:
wich is a VXP1747.
So, my theories are:
A) Someone, sometime long ago switched the upperd head of the AG4700 from VXP1747 to a VEH0651. Wich seems to be possible. (or the entire deck, since both are K mechanisms and are exactly the same).
B) At some point Panasonic decided switch the VXP1747 to VEH0651 heads. Since this is one of the late AG4700's, could be it has the "new" head.
Weirdly enough, in our local electronic market theres a guy selling two used videoheads...
you guess'd wich models? VEH0651 and VXP1747.
So, for those with HS1000 and AG4700 decks looking for heads, look for VXP1747 or more probably to found: VEH0651.
