I use push on cables in my system, because I'm constantly switching out tuners and most of the time I'm not concerned about getting the strongest signal. I know they worked fine with the TX-1000 and 2000. One just left here a couple weeks ago. I took a push on to F adapter and tried to put push it on the T-85 although the center conductor on the T-85 is hollow, it is too big for the center conductor of a push on. The PAL adapter makes good contact actually connecting around the outside of the hollow center.
