Anyone know where I can get a schematic (for a
reasonable
price) for an HP606A signal generator with S/N Prefix
842?
The one on BAMA isn't correct for this S/N.

Thanks,

What area is different?

I'm not sure (and I should mention I meant to say I was
looking for a
manual, not just the schematic)

There may not actually be many differences. The serial
number prefix
it shows is for 0960A. I looked again last night and
there's an
"Appendix I" that covers the changes for the 842 prefix so
this manual
may be the correct one after all.

I restored one not too long ago. Learned a lot
including how to restring the drive cable. I must have
worked on many 606As and Bs when I worked for
Hewlett-Packard many years ago but was appalled that I
remembered so little about them. On mine the rotors of the
tuning caps were decentered and the plates had been severly
bent to compensate. I had to disassemble the thing enough to
remove the caps and fix them. I have just the vaguest memory
of something to do with the caps in these guys having
problems. Generally, -hp- stuff of this vintage should set
up better than specs although there were some real dogs such
as early 400D/H voltmeters which were completely redesigned
about twice, and some early 200CD oscillators which had
several revisions of the circuits particularly the power
supplys. I dont' think there were any really serious
revisions of the 606A but can't be certain.
Agilent has many -hp- manuals on line in reasonably
hi-res PDF form, they may have a better copy than you have.
There is also some stuff at the HP Memory Project site.
