I am a big believer in "divide and conquer. Inject a signal at the center of the volume control (the terminal with cap # 41 connected to it). Strong audio will show that the amplifier is good. Agree with the others who state to check the power supply wiring.

Did the radio work before recapping? If yes, recheck the wiring and the caps used.

Check the caps that were replaced and the wiring. Check the resistors. There are several B+ "bypass" caps for screen grid and 1st AF plate voltages. If they short, or leak, they will affect screen voltages. Check voltages at resistors 57, 23 and 22. these act as a voltage divider that sets voltages for plates and screens for the converter (6A8), IF (6K7) and 1st AF (6Q7). Consider just replacing these resistors.

Low screen voltages or tubes that don't draw current can cause high plate voltages.

One other issue that can cause "motorboating" (The thump - thump noise, when fast enough sounds like a motorboat) is the AVC cap, #8 on the diagram. Note that it is on the other side of a ganged wafer switch, but should be in-circuit for all positions. I don't know why they placed the cap on the other side of the switch. Ohm this section to ensure continuity.

Hope this helps.
