The only advantage the 800A really has is that it includes some of the newer tube-sockets while keeping the four-pin and up sockets, and it is a "newer" (60s) tester. I have one and it is very acceptable.
The TV-7 is an excellent tester, well built, easy to calibrate and easy to use. My only gripe is that it does not measure directly in uMhos, although it IS a mutual conductance tester. It is also VERY pricey.
My ultimate testers are the Western Electric K15750 or the Triplett 3444, neither of which I own.
In addition to the 800A, I also use a Precise 111 and a Triplett 3423.
