[Test-Equipment] WTB, Tektronix scope parts

[Edward Greeley]

Good evening,

I just purchased a Tek 7844 dual beam scope that is in very nice
condition and seems to work well - except - something seems to have
struck one of the two concentric Intensity/Focus controls. The knobs are
shattered and the inner shaft is jammed.

I need the dual concentric pot, and both the inner and outer knobs. Used
would be fine, and NOS would be fantastic!

The pot is Tek part no. 311-1592-00. The front section is 2.5K
(intensity) and the rear section is 1.0 Meg (focus). The outer shaft is
1/4" dia. and the inner shaft is 1/8" dia. It's a little Allen-Bradley
pot that is about 3/4" square.

The outer knob is Tek part no. 366-1164-00. Typical 7000 series gray
color, with the shaft hole all the way through to allow for the inner
shaft. The bottom flares to 0.7" diameter.

The inner knob is Tek part no. 366-1146-00. Also gray color, fits the
1/8" shaft, and has a diameter of about 0.38".

Any leads on these parts will be greatly appreciated. I understand that
an ex-Tek employee in Oregon named Dean Kidd might have some of the
parts. Is he possibly a subscriber to this list, or does anyone know his
e-mail address? 

Thanks for reading, and kind regards to all,
Ed Greeley
