Thanks, Guys.

I thought that I had posted this reply earlier today, but probably I didn't notice that I had been logged off before clicking "post quick reply."

My primary question was about the discrepancies in the C+ jumpers (straps?):

Atwater Kent says: C+ to A- to B-
ARBE III says: C+ to A-
K-101A says: C+ to B-

Although I'm not sure why, my guess is that all three configurations are functionally the same. Am I right?

I may try experimenting with these configurations to see what the output voltages are.

Regarding the B- to A plus/minus discrepancy between Atwater Kent and ARBE III--I've been using the ARBE III setup, and it works OK.

Thanks again. Sorry for the delayed response.
- Henry

They are not quite the same, since there is a 5 volt or so difference between the two points. Either way may work ok, but the bias and overall plate voltage relative to the "cathode" will be different.
