The manual is at home (I'm at work), but I think it said something like 50
or 100 feet. Mine is about 50 feet away with no apparent problems. Skin
depth at 60 KHz is much larger than at HF frequencies, that's why the
shielded RF amp box is so thick.

Thank you. Do they give a number for the distance between the receiver
and antenna?

The HP117 manual cautions you to keep the antenna far away from the
receiver for just that reason!
Take a good look at the electrolytics, even the tantalums in the shielded
box. I had to replace most of them.

When someone posted the message about the HP 117A being on eBay I went
and placed a bid on it. I won it and am looking forward to firing it
up. I already have the HP loop antenna with the newvistor amplifier. I
have been trying to build a receiver of my own for the antenna but it
seems a lot harder to keep things from oscillating at 60 kHz than it is
at 14 MHz.
