Used high quality 10 AWG on the three Grey primary wires, and 10 AWG Yellow on the center tap lead of the 5 VCT rectifier tube ( the amp's B+ feed with a directly heated rectifier ) and 10 AWG Blue on the center tap lead of the approximately 800 VCT high voltage secondary.

The "end-to-end" leads of the B+ windings ( high voltage secondary and rectifier winding ) is 12 AWG. quality wire, twisted White in color, as we can plainly see.

This transformer is low DCR. Has an under one ohm Primary winding DCR and a under 10 Ohms secondary DCR, end-to-center tap. It will boggie with the best of them. Unit weighs 18 pounds.

Enlightened audiophiles regularly use 10 AWG special power cords to their amps, and report audible improvements. How about using ten AWG for all the 120 VAC wiring inside the chassis, Fuse, On - Off switches, right into the windings of the power transformer? Did so !!!

This will be my best-wired power transformer to date. It is going into a re-do of the 2A3 stereo amp I once posted here, where I get to apply new parts, and new understanding to my build. 'Will post - as I proceed. This was just tonight's work.

Cheers, and always remember this, an inch of bad wire can ruin the musical experience.

You certainly are confused and misdirected.

This is MY personal-use power transformer, one I designed as to specifications and had wound for me, to be used on MY new stereo 2A3 amp. No wheres in the thread do I mention Serious Stereo, and this thread has ZERO to do with anyone buying my friend's commercial gear !!

"One inch of bad wire can......."

"Prove it......"

Prove it to yourself. Take a stock Eico HF80 receiver. It has a 5/8ths to 3/4 inch length of bell wire lead across the amplifier section's input tube, as a direct couple from the plate of the input tube to the phase splitter's triode grid, the other half of a 12AX7.

Replace that 5/8ths of bell wire with a short length of very high quality wire. Why not TWO Kimber Kable AGSS, or some 13 AWG Siltech. Listen to that and you will understand what I am talking about. Right now, you don't have a clue. Prove it to yourself, for yourself, I already have, years ago.

"Use your ears......"

"My ears love distortion........"

Our ears are the very best measuring device we have in audio, the measuring device that counts the most.

Designing for "lowest distortion" is a misnomer, and only PART of the design process. Want lowest distortion, buy a solid state receiver with lotsa feedback. Our ears know when its right.

"Fulton, blah, blah,blah.....Fraker,blah,blah,blah"

"This is esoterica, known only to the initiated"

That is your problem, certainly not mine.

"Show me the math and measurements"

"I can't, its all in my head"

100 years of math and measurement failed, on its OWN, to produce a really great sounding tube amp. Its not in my head, but on either side of it, my ears ( and your ears ) IF you were to take the effort to listen. Many good people on this Forum and in audio do listen and listen well !!!

"Buy an amp from serious stereo, PLEASE"

Hogwash. You likely can't afford the gear, and so can't I. No wheres have I mentioned Serious Stereo in my post above. Nor is there an inference, except in your mind. Again, its MY power transformer re-do and MY amp I was discussing. If you have a problem with what I do, or what I post about, sorry... you don't have to read it.

Your sad flame attempt has little to do with the subject at hand. Cease and desist please. Thank you.

Nice post and explanation. Use what you want. I am not here to dictate what you must use !! I have A-Bed almost all of what I write about, so I have tried all I discuss. I am most happy using wire, similar to yours, but lower in AWG. YMMV, fine !! One size does not fit all.

Regarding chokes, a large size and weight I do not seek. Recall, I want low stored energy, so my choke of choice will weigh 2 pounds or less, easy to fit below deck, and I prefer 10 Ohms or less DCR.

As long as we are HAPPY in our hobby, that is what counts in the end to my way of thinking. Hi to Andy. Cheers.

I have to re-do the blue ( 843 VCT ) ground lead, later today, as I made it two inches too short. Maybe I will post a bell-cover-off photo of my "hack job " - as you would like to call it. Everything is double heat shrinked for safety Gusser.... A.M.A. approved by my cardiologist and pastor.
