OK, here's the question. Do INDIRECT heated rectifiers (6X4)require unique winding configs (phasing) for proper operation, and here is the scenario on this Heathkit 54-34 I'm rewinding. Inner windings (HV) wound as two separate 1285 turn sections same direction. Start of inner section tied to end of outer section to create center tap. Remaining 2 leads connect to plates. Outer windings(LV fils) is 2 separate 40 turn layers, but wound in opposite directions, with start of the inner section tied to end of outer section, and start of outer section tied to end of inner. Its all done, looks great, but unfortunately forgot to counter wind the last separate outer layer, and will need to remove it. I've used thin cotton adhesive tape and shellac between layers as insulator/binder. Any comments PLEASE??

I also have a question. Why in the world would you think they would? How many years have you been at this?

The 6X4 doesn't give a hoot about the phase of it's filament supply, if that's helpful. It just wants it's 6.3 volts amd fimctopms as a lamp. The cathode is indirectly heated and not connected to the filament in any way (unless the tube is shorted.)

And the rest of the set can use the same 6.3 volts from the same winding, provided that the total load is met.

So, have you created two windings that each have 3.15 volts? If so, connect them in such a way that you wind up with 6.3 volts. Phase does matter here. I'd try setting this up with a volt or two source on the secondary, and measure the primary to gauge what is correct without the possibility of destroying your work. Hope this is helpful.
