[time-nuts] HP 106B quartz frequency standard...the story so far

[Jim Palfreyman]

OK folks, I've rechecked the voltages and here's the details.

Firstly, changing the oven temperature screw was a mistake. Read a
previous thread to see why I did it. It was logical given my
experience with 10811 ovens. I've owned up to it and begged
forgiveness from the great Flying Spaghetti Monster. It never answered
so it must have made me do it. Please drop that now. :-)

When I first powered the unit up it had bad and leaking NiCd batteries
and made a horrible sound. I removed those and I presume something was
damaged.

The "input" voltage to the 2N1701 is normal (according to the front
panel meter) and is close to 26V. The "output" voltage is 25V and not
18V as the manual says. I have the manual now and anyone (with more
experience than me on old fashioned power supplies) who wants to
comment I am happy to email the circuit diagram and eagerly await
comment!!!
