Setchell Carlson...588 dial, 407 cab, 420 chassis(?) Serious need of a schematic.

First you need to put the grid cap back on the 6A8.

Measure the supply voltages on each plate and screen grid. You should get at least 50 Volts or up to about 100 Volts. See that the cathodes all draw current. Then see if the local oscillator is running. You really need an isolation transformer and an oscilloscope to do this properly.
