OK I was doing something stupid.  The wire from terminal 3 is fine...it reads infinite resistance to ground.  The wire from BC resistor terminal 4 is the same readings as before...90.4k ohms with the speaker unplugged...3200 ohms with the speaker plugged in.

Pics show these 2 readings, the speaker socket and the general area around the speaker socket.  All tubes are out.  In the last pic, that small black box attachment is for a 1/4" jack input for Bluetooth and similar input.  Pretty sure it's not an issue.  Radio and it worked fine before.
