[time-nuts] Other HP 10x manuals (was HP 107BR)

[Bill Hawkins]

Brooke,

My first 113 arrived dead. Found the fault and replaced one
of the two big electrolytics in the motor drive circuit. Is
that something you can do or would you like someone to fix it?

I've lubricated the gear mechanism (much simpler than an R-390)
but I figured the motor bearings were sealed and shot. Never
tried relubricating them. I kept the clock inside the same
insulated compartment as the oscillator because of the noise.

HI Jeffrey:

I have the following equipment looking for manuals:
107BR
113AR
114BR
HO3 115BR

My 113AR ran for many years then quit.  I had it in the garage since the
1 kc wine would drive you nuts if in the house.  Also it was unbearable
if the drawer was cracked open.  Best to have all the front panel screws
  installed and tight to contain the sound.  I had to replace the photo
interrupter and also added an input circuit so it would take TTL level
pulses.  But is sure is nice to see mechanical hands.

Have Fun,
