There are some more components around the 25L6's but the above should cover the most important ones (I hope!) Get the above straightened out before proceeding.
9. 6Q7: pin 3 (the triode plate) goes to the interstage or input transformer that feeds the two output tubes. The other wire coming from that side of the transformer should get B+ to feed the 6Q7 from somewhere, probably from the + side of the second electrolytic filter cap? Check ohms between these two transformer wires: transformer should not be open or shorted.
10. 6Q7: pin 8 (cathode) either goes directly to ground or to ground through another component or two?
11. 6Q7: top cap (grid) should go through a cap to the center terminal of the volume control. Can't tell from the pix but this line should not be grounded anywhere or any signal will be shunted to ground and there will be no audio. Test: remove the clip from the grid cap of 6Q7, turn set on and volume up, touch grid cap. If loud buzz, audio section is working and something seems to be shorting out signal back to the volume control.
