The intermediate stages are carefully phased to 456 KC at the factory. Should rephasing be necessary, attach the output lead from a 456 KC test oscillator to the grid cap of the 6A7 tube, keep the signal to a very low audible value and carefully adjust the two trimmer screws in the top of each of the two tall cans to loudest volume. If an output meter is available it should be used across the two black leads at the speaker transformer. An oscillator covering a frequency from 550 KC to 16 MC should be used to rephase the R.F. The test oscillator output is attached to the aerial lead of the set. At all times keep the oscillator signal turned down to a low point of audibility. Trim the shortwave band first, then the broadcast band, setting the dial pointer to a frequency near the high frequency end of the scale in each case. The short-wave oscillator trimmer is located directly across the large (oscillator) coil looking at the under side of the set, and the R.F. short-wave trimmer at the right hand end of this coil. The broadcast band is next trimmed at the high frequency end of the broadcast scale, applying a signal from the oscillator corresponding to the dial setting and adjust the oscillator trimmer connected between the end of the oscillator coil and the porcelain base trimmer. Next trim the Broadcast R.F. by the trimmer connecting to the band switch. The broadcast band is next trimmed at the 550 KC end of the dial by adjusting the porcelain base trimmer at center of chassis until the signal is heard at the correct location on dial.

The intermediate stages are carefully phased to 456 KC at the factory. Should rephasing be necessary attach the output lead from a 456 KC test oscillator to the grid cap of the 456 tube, keep the signal to a very low andible value and carefully adjust the screw. in the top of each of the two tall cans to loudest volume
Output meter is Available it should be used across the two black leads at the speaker transformer, An oscillator covering a frequency from 660 KC to 16 MC should be used to rephase the R.F. and the oscillator output is attached to the aerial lend of the set At all times keep the oscillator signal turned down to a low point of audibility. Trim the short wave band first then the broadcast hand; getting the dial pointer to a frequency near the high frequency end of the scale in each case. The short-wave oscillator trimmer is located directly across the large (Oscillator) coil looking at the underside of the set and the R.F. short-wave trimmer

At the right hand end of this coil. The broadcast band is next trimmed at the high frequency end of the broadcast scale, applying a signal from the oscillator corresponding to the dial setting and adjust the porcelain base trimmer at center of chasain until the signal is heard at the correct location on dial.
PHONOGRAPH Install a single pole double tbmw toggle switch in rear flange of charris near right-hand end. Disconnect .01 mfd condenser from volume control and connect to one side of switch, connect volume control to center terminal of switch, connect one side of phonograph pickup to other side of switch and remaining pickup terminal to remaining outside volume control terminal.

Short-wave Oscillator trimmer attaches between the two ends of the oscillator coil located at the right. Broadcast oscillator trimmer is the lower section of the dual trimmer at the end of the chassis, Short-wave R.F. trimmer is at the lower end of the oscillator coil and the broadcast R.F. trimmer is to the left of this same cou).
PHONOGRAPH - Install a single pole double-throw toggle switch in rear of chassis nearest the 75 tube. Disconnect the .01 mfd. condenser from volume control and attach to one side of toggle switch, connect middle terminal of switch to terminal of volume control just disconnected, connect one side of phonograph pickup to retaining terminal of switch and other side to " B " minus.

An all-wave oscillator having a range from 150 KC to 20 MC will be necessary to rephase the frequency bands. The oscillator output is attached to the serial lead of the'set and oscillator output kept always at a law audible level. The.R. F. coil trimmers are reached through a series of five (5) holes in the side of the R, F. shield cans and correspond to frequency band Nos. 1, 2, 3, 4, and 51 from top down, The oscillator parallel trimmers are seen on the underside of the set when the front of it is raised and are located along side the band switch, No. 1 being the one nearest the back of chassis and No. 5 nearest the front. The dual porcelain trimmers at back of chassis are series padders, the

Left hand for band No. 2 and the right hand one for band No. 1. The series padder for band. No. 8 is the single trimmer at the center of the chassis, Each band is trimmed first at the minimum end of its range, band No. 5 being first, No. 4 second, then No. 3, etc. Bands 3, 2, and 1 are also tracked near their maximum ranges, or with the tuning condenser turned well in, by adjusting that series padder belonging to the particular band being used, location of which is given above.
