I have what is labeled on the dial plate and inside the top cover of the console as a Freshman Masterpiece. The difficulty I am encountering is that this is a six tube radio (3-RF, 2-audio, 1-det). The only schematic I can locate to date is for a five tube set. I have found a serial number plate reading 14419. When looking at an antique collectables book I found a description very close to my radio for model number 7F5, but a schematic for that model number has eluded me. Any help is greatly appreciated. Thank you!

Hi Lee

A lot of the old battery radios are not shown in Rider. However most of these radios are similar. You will be able to find schematics for Stewart Warner 300 series. Some of these are 6 tube. The Atwater Kent Model #30 is also available. Except for the extra RF stage the schematic that you found should be close.

Hi Lee, The Equaphase is on the same page in Riders as the Masterpiece and uses six tubes in the arrangement that's the same as yours. You might have this schematic already but I'll email it and you can see if it's usefull. Good Luck, Don Black.
