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 could use the 608 modulation meter and shunt it to make a 50 uA meter. That's a joke yall.

Oops? I looked up the meters in the 608D manual and I find that the two are
not identical. The RF level is 50 uA while the modulation is 1 mA.
Unfortunately I need the RF level for the 608. In the case of the 606 the
PDF of the manual I have is not very clear and I couldn't find the meter
listing. I think they are both 200 uA meter movements. I had to shunt the
100 uA meter I kluged in to be able to calibrate it.

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 identifies it as a 200ma movement).
M2 (RF Output) is as a 100uA, part number 1120-0074 (listed as a 100ma movement).
Cheers,
Dave M
