Found that both of the large bypasses were bad. One was leaky and pulling down the voltage on the 24A detector tube. BC resistor is running a bit cooler with 90v on the ac line. The speaker had a bad connection at the voice coil so it's work too. Paper is stiff it doesn't produce the volume the replacement did. And one of the 71A's died rip.
