Is a good place to get help and advice from other HP owners.

I ordered some of the 8640B gears that the guy in Italy casts, just to see what turns up.

(Mine aren't cracked now, but having spares insures that they never will fail, 
especially if they are stored where the 8640B can see them...)

Got a new generator for the bench-an 8640B with option 004, the 1dB step
attenuator.  I'd like to add option 001 [the continuously variable audio
oscillator] to it, and I understand option 001 is retrofittable, but as yet
I have no clue where to go for parts or documentation.  Even without option
001, it's still a very nice tool.

I got my first HP-8640B last week.  It has Option 3.  I've done a small amount 
of fixing to it, but nothing very major.  I'm lovin' it.

Is Option 3 the frequency doubler extending the range to about 1 kmc?   
(kHz)

The 8640 I have here does not work on FM.  If anyone has a spare FM  
board, I might be able to buy it and fix my generator,

Option 3 is Reverse Power Protection.  Mine came with one of the cards necessary 
for the frequency doubler, but there is additional circuitry required to make 
that option fully functional.

The gears in mine are cracked but not separated as much as some I've seen.  
Still thinking about how I want to make that fix before they get worse.

Good luck with the FM board.  There are a lot of individual boards on eBay but 
they're pretty high in price and no guarantees.

I was just out on the Simple Green website.? Per the site they distribute 
through W.W. Grainger, Fastenal, and Sherwin Williams paint outlets as well as 
McMaster Carr (if you don't mind paying shipping) to mention just a few common 
sources.? Available in a variety of sizes up to, and including, 55 gallon 
drums.? They even recommend it for engine cleaning which is kind of interesting 
to me since I also restore cars.
