Try this. Very simple mod, but it really opens up the audio on these old tube sets. Be certain to use the correct voltage ratings on the diodes/capacitor.

To get a little more gain on the mic preamp, change the bootstrap cap C63 to a .22uF 50V or higher. Need a little more? Change R62 to a 100K, 1 watt.
