It appears to me that the 3.58 osc is not working. Measure the negative grid voltage on the oscillator section of the 3.58 osc. tube. It should be around -7 volts. I had a bad 3.58 crystal in one set...hooked up a known good xtal w/alligator leads and got color.
Also the plate voltage on the osc. tube will be high because the tube is not drawing any current through the load resistor if not oscillating...make sure also that there IS plate voltage at the tube. Do you have the photofacts/schematic...it's a lot harder to do this troubleshooting without it.
