RE: 6X4 Rectifier Questions

TK gave you a warning, specifically about the 6X4. You can use the schematics with ZERO signal parts changes and a Loctal 7Y4 as the rectifier.

Don't mix apples and oranges. 5 V. types, like the 5AR4/GZ34 and 5V4/GZ32, have the cathode sleeve tied to the heater at pin 8. The construction is known as 1/2 indirectly heated and, like the directly heated 5U4 and 5R4, require a dedicated, separate, filament winding. Types like the EZ81/6CA4 and 6X4 electrically isolate the cathode from the heater and, as TK pointed out, can share the filament winding with signal tubes.

BTW, an advantage of 1/2 indirectly heated construction is that heater to cathode potential issues can't be present.
