Yes, but in actuality, you can very often pick up a good 465 or 475 for
$100 or so, take it home, clean it up, and it will work for you for
years. That's hard to beat. 73 de Alex NS6Y.

Hi
In interesting piece of trivia. The DM44 sensor in the temperature probe is
a 2n transistor. The circuit is similar to the temperature measuring
circuit in the KPA100 used to monitor the heat sink temperature.

Hi
Be careful buying older Tek scopes. Many of the repair parts are not
available any more. You may get lucky and never need to repair one of these
scopes but many of the parts were proprietary made custom for Tek or in the
case of some of the IC's and CRT's were made only by Tek in there own f
I have a 475 with the DM44 option, and a scad of different probes.
It is on "semi-permanent" loan from my company (they have no need for it
any longer). I have never used the DM44, but what looks interesting is
that it will measure temperature in degrees C. I have the temperature
probe and w

Dale,
You are correct that batteries provide a good stable source of power. Just
remember that they can pack a lot of current, and they do not protect
against a short circuit condition like a power supply will - if the battery
terminals are shorted they can provide enough current to melt wrenches

Well, if you hear sidetone, you got it right!!! It is no more complex than
that, and there should be no uncertainty in your mind.
The real problem is that folks don't know where to look first if the

The selectable sidetone source is for support of older K2s that have not had
