Tektronix 465B DMM44 restoration

(1/1)

krisztian_andre:
Hello,

I'm repairing and cleaning a tek 465b that I bought recently. I couldn't find a partslist for the dmm44, does anyone know the part number of the knob on the multimeter? Mine is broken. Also, what kind of bulb is in the grid illuminator?

krisztian_andre:
All the service manuals I found have mussing parts on the left and right sides of it's pages. If you have a manual with full unclipped diagrams please let me know.

Thanks. You've reminded me of a weird piece of history. I never understood why anyone would buy one of those overpriced, clumsy to use, poor performing multimeter add ons for a scope. There were quite a few around at one time, though.

I never really liked the idea either but some of them doubled as the delay time and delta delay time readout on oscilloscopes which had delayed dual sweep and delta delayed dual sweep timebases.  You can tell which ones support this because the delay time control will not have a mechanical readout.

As far as the service manual goes, try contacting Artek Manuals.  I am sure they have complete scans for a low price.
