Missed this. Pretty heavy but not 100 lbs. I used to work on 620, 616, 614 generators and could manhandle them without too much trouble. These and the 608, 612, etc, were built like steam

Are you aware the very cheap DMMs are often only 1 Meg input resistance instead of the 10 meg in better meters. They can still be very useful as long as you realize they can load a high impedance

That helps. Thank you. Finding the modulation meter would be nice but if I found the RF meter I could shunt it and change the scale. If someone could tell me where to find a negative resistor I

I have an old HP catalog which does not show a year but the picture on the front and back looks like an aerial view of the ocean with many things superimposed. They include a rocket, an Atlas Centaur

If I recall correctly, I believe that the sliding portion of the attenuator can be removed from the fixed portion to effect repairs on the resistors and capacitor but it is ringed with spring fingers

Max, About the meters for the HP 606... I have the manual for the 606B, which lists the meters in the parts list. M1 (Percent Modulation) is a 200uA movement, part number 1120-0075 (the parts list

I have a Boonton 42BD Microwattmeter with a digital display and use it often. Im guessing a mid 70's product?

Really? I thought I've seen Boonton instruments younger than that. Did HP keep the Boonton name for a while after the acquisition? Dave

If the handle is what I think it is, it is malleable steel. A hammer would be fine, but use some wood between the hammer and the handle to avoid scarring it. Or, depending on how it is bent, a vise

Thanks for the advice Chuck, I'm trying some epoxy on the bezel as we speak. Not sure what I have that would bend that handle... it's a monster. How do you think beating it a bit with a hammer would

This is confusing (at least to me), because there was Boonton Electronics, Boonton Measurements (usually just called Measurements), and Boonton Radio. HP bought Boonton Radio, but not the other

I think the IF filter architecture of the 70902A may be roughly the same as in the 8566. If so, those crystal filters are all 3.0 MHz center frequency, with the bandwidth set by controlling the load
