Realignment of this receiver should not be attempted except by an experienced se'rv1cem&1\
and only after all other possible causes of faulty operation have first been thoroughly
invest igated. An accurately calibrated signal generator which will cover the necessary ,
wave bands is required. Either a suitable output meter or the cathode-ray tuning indi-
cator may be used for indicating tue effects of adjustments. It is necessary, in all of ~\_/
the ensuing procedure, that the signal generator be attenuated as much as possible.
- The 1. f. transformers are housed in the polished metal shield Qn the
chassis. The location of these transformers is indicated in the acoompanyirg din, ram-
The trimmers are on the tops of the transformer cans. The first and s eeond i. f. grams-
formere have two trimmers each and the detector coupling transformer has onli, one trim-
mer. fhese trimmers are adjusted at 456 ko. for maximum g ain. In making; this adjust-
ment , the oscillator (rear) section of the tuning condenser should be short-circuired _
and the signal generator connected between the grid cap of the 6AS and the ground past
of the receiver. The selectivity switch should of course be in une hicvh selectivity
SHORT WAVE BAL-"D - With the output from the signal qgnerator connected across the Q91-ig_1
and grcunE terminals of the receiver, and the volume control in position for m&Ximnm
volume, the oscillator trimmer for this band is adfiuqted for maximum response as indica-
ted by the 6E5. This adjustment must be made with the dial set at exactlv 17 mc. ,
otherwise the calibration ni 11 Yoo off. The series Qadder for this band e hnuld than be
adgusted by setting the signal generator at a freguencv of 5.5 megacycles and tuning \-"
_the signal in on me receiver. The tuning condenser is ro cated slightly back and fm-th
as the padder scre?` is ad usted for maximum output. The 1? mc. adjustment shnuld thgn
be rechecked. If tue dia calibration is off, the nrocedure should be resented again.
