I would think that it maybe a weak 6GM8. The tuning is not done with a tuning capacitor but be moving a metal slug though a coil. This is called inductive tuning. So there isn't much to clean. A8 looks to be the oscillator adjmnt this is use the set the frequency at the high end of the band, A9 is the rf adjmnt this will make the stations near the the high end of the band louder IF it is out or alignment. Would clean up the tube sockets by spraying some Deoxit on to the tube pins and then inserting them a few times. Also switches too.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
