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. http://www.tmitransformers.com/ 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. |

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. |

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? |
