Greg,
Could you explain a bit more about how you would make gears for the 8640. I understand the cracking is a rather common problem. Mine has cracks but is still holding together and functioning. That said, a spare set of gears would be a good investment should bad things happen.

Greg,
I would be intersted in two sets of gears if available.
Let me know.
Thanks

I recently learned my 8640B does 1GHz. Seems when I built the unit, it included the high output module which was one I found installed in the stack of as/is units I bought pretty cheap at a hamfest.
Anyone need extra gears for their 8640? I'll make some if anyone wants them.

Internal. Actually an integral part of the output power amplifier assembly.
Complete output module is changed to extend an 8640 to 1024MHz.

I read in the HP brochure which Pete's link pointed to that the 8640 did
512-1050MHz through a powerdoubler.
I have that generator but I alway wondered if the powerdoubler is inside or
external. I thought the latter but now I'm in doubt. If external what was
the partnumber so I can find a schematic.
