I'm not certain about that; while I haven't used an 8140 amplifier, I have an 8164 WWVB disciplined oscillator that has an option installed to allow it to run a string of 8140T taps. I was able to use those outputs directly by using a series cap to isolate the DC voltage; what's left is the 10 MHz sine wave. As I noted in my other post, it does want to see a 50 ohm load (after the isolating cap) or the fault indicator may go on. I suspect the 8140 amp is very similar; Spectracom did a lot of design reuse across their products.
