With speakers (or headphones) connected & unit powered ON: A smallish-value capacitor (the lil' orange 0.01uf/400v metal film from Radio Shack will do) with one lead held between thumb & forefinger & the other lead touched to the control grid lug of each tube socket should produce a hum as heard from speakers (or headphones) if the stage is OK. IOW begin this procedure from the output & work back towards input one stage at a time to discover the stage that is not passing signal. When no hum is heard, thouroughly check that particular stage (tube & all supporting circut parts). BE CAREFUL, dangerous high voltage exists on nearby tube socket lugs. Discover schematics by inserting hhscott inbetween the ubiquitous www dot dot com.
