It was not always the case that Tek saw HP as a rival. At first things were friendly since Tek held most of the scope patents and HP had no choice but to use them (legally) when they started making sc

After several false starts, hiccups and a gaffe, I have the TWD120 graciously provided by Charlie Conger fully operational. I won't go into great detail but will touch on all the issues I dealt with.

A free 7704A showed up here and seems to work 'OK'. I noticed the heatsink was REALLY hot to touch. The measured temperature is 130F / 54C. Is this in the normal range? (Yes this is a cross-post from

Howdy folks, Anyone have a PAPER manual for the Tek 5D10 plug in for the 5116 scope that they would part with for a reasonable amount? Thanks. Dan (kaboomdk@... and I'll take replies off-line).

I have a TM5006 power frame that does need a capacitor refresh. My unit is one of the early production, and the ripple is bad. Does any one have a recommendation as to a brand or type of capacitor to

Hi folks - quick intro since this is my first post. I'm a guy who wants to repair old computers/video came consoles, and about as green as one can be when it comes to using an oscilloscope. I'm not a
