I am spec'ing out amps for doing Bird wattmeter elements (mostly the Bird 43 elements) from various frequency and power ranges.  There are so many combinations of power and frequency that I won't list here.

If anyone has setups for Bird wattmeters, I'd appreciate any thing you could share.  I have found some models from Amplifier Research, some from ENI (I think out of business now??), a nice one from Ophir, model 5127, and some others.

There is also an OEM called E AND I that competes with ENI.  Most of those models seem to cover the lower freq ranges.  Any good recommendations of OEM's to use or not to use, models that work well for the application, etc.
