Follow Ups:
...Where they got a "jaw dropper" improvement by using a transformer 100 times larger than necessary in a preamp (link below), your speculation about a "better transformer" may be correct.
Their eventual conclusion was the lower secondary impedance of the larger power transformer which caused the improvement they heard
.
630mA compared to the original of 250mA. I could have went higher but I just wanted to see how this new output would sound first. I am really liking what I'm hearing with the new Antek transformer. Everything is just more from that of the original transformer. It just way better!
....about 15 years ago someone here recommended replacing transformers in a tube amp with the same output voltage but higher current, maybe 2 to 3 times as much. I used 2 new Hammonds.
I had 2 monoblocks running some Altec 604's and 515's and the improvement was quite noticeable. It's NOT imaginary.
Cheers!

...I will post the link to the article where Paul McGowan talks about Stan Warren's "discovery", and explanation.
The objectivists start to clam voodoo, until the explanation of lower secondary impedance is given. I've always built my power supplies with larger than necessary (for the circuit to function) transformers after reading that.
Do you still own your 604s?
I sold them here on the Trader to someone setting up a new Sterling Sound Mastering facility in Teaneck NJ. They wisely picked them up to avoid any shipping damage.
I kept the Onken type cabs and loaded them first with the 515's and now University C15w's with new surrounds. They are both about the same for sub use down to ~25hz. I run 3 subs and 2 woofers for my Quads, all barely breathing but giving a superb performance. I am quite crazy and devoted.
Long live AA.
