1929 Receiver

The 1929 receiver.

This is the main station receiver patterned around some 1924/1925 schematics.  It is quite stable and sensitive.  Radio uses a pair of 201A's, one for the detector, the other as an audio amplifier.  The output is fed into the 2 tube #227 amp.

A few small mods I've done since the article on this receiver was published consist of replacing the grid condenser to a 100pf mica and I also reduced the tuning capacitor capacitor to restrict the tuning range from 3500 - 3600 KHz.  Also, I rewound the grid coil winding using #20 DCC wire.
