A friend uses a couple of A-431-S in his 6550 PP amps and is very
satisfied
with their perfs: they're as good as or better than the originals.

Does anyone know who their really made by?


Dunno, but TMI looks like a possible source.

They may be made by Schumacher or any of four or five other outfits as
well. Chicago still has several winders. Schumacher has a good deal of
experience with opt's having wound for FMIC, Mesa Engineering,, STL
Music, and McIntosh.

The choice of Dyna iron-which is still readily available on the
secondary market-to reproduce is curious and somewhat (actually, very)
poor. A Dyna upgrade (which is what the power transformers are, several
companies wind those, some for bridge SS rectification and no 5V
winding) OPT would make more sense but the desireable OPTs are Marantz,
Mac, HK for OEM repros and Acro, Peerless and UTC for vendor catalog
products. The UK Partridges would also be desireable as well.

I second the recommendation. My Dyna-Clone MK3 Monoblocks use the Power
Transformer sold by Triode Electronics.

The power transformer is high quality, stable and free from buzzes or
mechanical vibrations even when I bias the KT-88 up to the full 70 ma.

The paint job is OK but really would need a spray of some quality finishing,
heat resistant enamel or acrylic.

Triode used to also sell the Magnequest line of Dynaco replacements. I
purchased a pair of Dynaco MK-3 MQ-782 transformers. They perform very well.

Cannot say how the current Dynaclone product work, but they do seem more
economical.

I did have to re-paint the MQ-782's. They are not empowered cosmetically and
need a final coat to make them look good.

The issue with the Magnequest products was delay's in manufacture. Mine were
back-ordered for 2 month's. The current product sold seem to be in-stock
from their web site descriptions.

Curcio sells the Magnequest clones that start with the MQ part number. The
prices are higher, but I also expect them to be equal to or better than
anything current.

I refuse to deal with Mike Lefevre on the grounds that he is a liar, a
mountebank and a windy fraud. Life is short, why support a cocksucker
like that? Even if he could PROVE his treansformers are any good and
even if he can PROVE he has them in stock and ready for shipment. He
will not prove either and if you ask him he will call you a
"trouble-maker" and tell you you have no right to ask him to do that.

So **** Mike Lefevre.

Well, what are the differences between Acro and Dyna iron?


They were interrelated as everything connected to hi-fi out of
Philadelphia was, Ercil Harrison was pretty much at the center of all
that transformer stuff. Now Mike Lefevre is to Ercil what Anna Mizrahi
Strasberg was to Marilyn Monroe, a dirt eating worm feasting on the
bones of dead people they never met.

Acro made the transformers for the Dyna products, but the Dyna
transformers were not of the specification of the Acrosound TO-series
transformers. Hafler had a patent on the Dyna transformers where in
order to make a transformer he could have cheaply wound, like a power
transformer, he sacrificed DC resistance balance in a big way.

Simply put, as far as AC is concerned a turn is a turn but the turns
on the inside of the core are much shorter and use much less wire than
those on the outside, therefore, have lower DC resistance. Along with
being smaller and lighter overall-less wire, less copper-than the
premium Peerless and UTC outputs the Dynas have unequal copper
resistance between half-primaries. Worse, the interwinding capacitances
differ somewhat.

The Dyna OPTs used in the ST70 and Mark series are a cost effective
rather than a pure performance solution. Amplifiers using them can be
pretty good-they are a good upgrade for guitar amps, in fact Sunn used
Dyna iron extensively-but will never be first rate. Replacing the
transformers with better ones on a ST7o can improve the performance,
unquestionably.

My beef with remaking the Dyna iron is that since it is still common,
why remake it and not a genuinely superior product?
