Ok both indications are good. Next take your signal generator and inject a modulated signal @ 455kc into the grid cap of the 6K7. Should hear signal in spkr if all is well. Then inject the 455kc signal into the grid cap of the 6A8. Again should hear tone in the spkr. Adj the output of the generator's output so you a just barely can hear it in the spkr. Adjust the IF trimmers for max output. If any of the IF trimmers don't have much of an effect you may have a bad IF transformer, but you know what to do in that case [Image: http://philcoradio.com/phorum/images/smi...n_clap.gif]. Will you be headed east in May??

figure out what all those squiggly meant.
