Antenna impendace matching for old tube receivers

Hello,
I've purchased an 1962 tube HF receiver. Well the problem is I don't know
exact antenna input impendence value of it. I use simple 40m. dipole on a
regular TV cable of 75 ohm. I would like to do some experiments with random
wire, and 50 Ohm coax or 300 Ohm ladder line for dipole. Is there any
circuit that can help me to mach the impendence?

Thx,
Edgar
