Unidentified Silvertone

Hello, Jay: I believe what you have is a model 1720 "Challenger." They were advertised as a 10 tube set at a 7 tube price.
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.
