Hi Tony
Yes, Model 71 is a very good performer. Just watch out for its autodyne mixer circuit, based around a Type 36 tube. The oscillator coil, a vital part of this circuit, will most likely be bad. It should be baked in the oven (NOT the microwave!) for 30 minutes at 200 degrees Fahrenheit. This will eliminate the moisture is has probably absorbed over the decades. Then, if the outer winding is bad, rewind it. If it isn't bad, consider yourself lucky.
