Figure 9.10 modified AA5.
Only the line connections and part of the rectifier will be described. The rest has been described in detail on Fun With Tubes.
The original line cord should be replaced with a polarized two prong plug and cord.
The wide prong of the line plug connects through the line cord to chassis or to radio common which in some models is not directly connected to the chassis. The other prong of the line plug goes through the line cord to one side of the on/off switch. The other side of the on/off switch goes to the rectifier heater and also to the plate of the rectifier. There is a capacitor from the plate to radio common. The other side of the heater goes through the other four tube heaters to radio common. End verbal description.
