1、MANUAL OF 1951 MOST-OFTEN-NEEDED RADIO DIAGRAMS The models listed at right with the suffix U use Chassis HS-224, the other models use Chassis HS-250. The circuit shown is exact for HS-250 using multiple capacitor-resistor plate. The insert diagram in the lower left hand corner shows differences in t

2、he HS-250 for a multiple capacitor plate. Chassis HS-224 uses both types of plates and differs from HS-250 in phy sical assembly and some circuit elements.
