The tube lineup for a 1720 is four-45s, one-6A7, one-37, one-75, two-78s, one-5Z3.
These sets have an "extended" broadcast band that goes (I think) to 1800KHz.
Hi,
The model 1720 is viewable at the Radio Museum site, shows a different dial scale setup, but other than that is real close. The 1725 uses a different cabinet so that's not it. The model 7065 uses the exact same chassis but cannot locate a pic of the cabinet so maybe it is still a possibility? All three models made in '33-34'. John
