The post above is sales talk for an R core output tranny. I am not sure how they are made but from the picture at http://www.icl.co.jp/audio/english/RX40.htm is seems the core is a spiral of magnetic material, probably GOSS with a high µ although perhaps the non oriented plain silicon content steel would be fine, since too high a µ can result in easy DC saturation with DC bias imbalances in the hlf primary windings in a PP amp, similar to what happens with toroidal strip wound GOSS cores. Don't ask me how they get the windings on, but I'd say the bobbins are in halves, and taped around the core, then rotated by special machine to draw the wire on to get a twin winding rather like Lundahl's use of C-cores. There are no details of the saturation performance, winding arrangements, interleaving an insulation details, so perhaps this tranny isn't as good as the graphs and info supplied suggest. The core cross section size looks quite puny for a 40 watts OPT. Nobody can check out the validity of the design because like so many makers they don't come clean with the nitty gritty details, all able to be expressed in a short paragraph similar to as used to describe the Williamson tranny of 1947 in RDH4. R-cores convey no special advantages over most other designs, except cheap construction in a mass production situation, and I wish the makers of this tranny the best of luck. I also wish they would actually tell us what they are really doing. In the meantime while I wait for the info I'd be interested to see and to discuss, and which has been non forth coming for years now, I will never buy their product, but continue to wind my own. Patrick Turner. |

"Steve Dolan" http://www.icl.co.jp/audio/english/RX40.htm ** Nice tranny - nice price. The only issue is the need for close tube idle current matching ( 5mA) Better have external test points and an accessible trim. .............. Phil |

But its true Phil, this design only suits those with mass production facilities and acces to Rcore making jigs et all and the special windinging machines. They churn 'em out cheaply. I also wish they would actually tell us what they are really doing. ** The specs are quite comprehensive. There are no details of the winding layout, thickness of insulation, interleavings, and wire guage and turn numbers, weight, core material details, dimensions etc, etc.. All that is part of a real specification. The claims made by the maker are mildly impressive, but it takes more than claims to convince me of anything. I am not a silly gullible unfortunate like yourself. Delete more obscenities... Phil suffers from bi-polar syndrome, which is a psychological condition which disables him from conducting any rational peaceful discussion. He thinks he's ok and the whole world is wrong when he hasn't taken his medication, but we all know he isn't ok at all. No use protesting Phil, we already know what you might say. Patrick Turner. |

Yes, but after the vicious attack on Turner, is anyone now prepared to
listen? He likes to wind his own, which is fine, although I do wish he'd wind the good American kind like Mac, Marantz or Linear Standards, or even Peerless to **** the nut in Philly off. |

Not vicious, just how he is. He was right to help Patrick find the data for saturation, although he could do with finding a definition of saturation better than the one he seems to use.

A clear statement of full power bandwidth with the correct load, and some indication of distortion characteristics at the claimed lower limit would be helpful. All that stuff about "we tried it with pentodes so triodes must be better" is suspect and silly if it is intended for triodes. Also useful would be info about what the core is made of, and what the leakage and winding capacitances are. Perhaps I missed that? Perhaps a direct comparison with, say, Plitron? I think Patrick is quite right to doubt its low-frequency performance. Who is the manufacturer, BTW? Are they available direct? No point in talking to the monkey perhaps. cheers, Ian |

He was also entitled to point out Patrick's evasive and typically dishonest squirming. You are quick to gather round and plunge a knife in like the the other jerkoffs. The address I went to to get the full story about R core OPTs lacked the items I listed, size, weight, core type and iron µ, turn count, wire sizes, insulation thickness and type, winding layout, layer numbers, interleavings, etc, etc, etc. Don't let me stop anyone from buying an R-core tranny; be my guest. But don't swan around here saying there is everything to be known at the R-core tranny site, to enable someone like me to do the simple math to see if it could work as claimed. At my website, i do give a recipe for at least a half decent OPT, and the full amount of information is there, free, and for anyone to use to wind, or to contract anyone else to do it for them. I also give all the formulas you'll need if you wanna desigh from first principles I am the one to have the transparent approach, not this R-core mob. The graphs look nice, sure, but that's all not enough for me. This group worships no sacred cows, and if somebody brings to us something for sale, then let us analyse, let us be testing, let us be difficult, and if the hawker has any sense, his briefcase will be full of convincing answers to all our questions. With no answers, the hawker is a mere spammer. He was wrong in saying the tranny is good though. Good enough for someone, somewhere, who didn't have a clue about OPTs, which is nearly everyone. A clear statement of full power bandwidth with the correct load, and some indication of distortion characteristics at the claimed lower limit would be helpful. All that stuff about "we tried it with pentodes so triodes must be better" is suspect and silly if it is intended for triodes.

No point in talking to the monkey perhaps. cheers, Ian Unfortunately, we just don't know enough detail to confirm if the designs has the actual charateristics as claimed. They are apparently inexpensive, so buying to find out isn't such a bad option if you have the money. But how many ppl know how to measure something like this? Not many. At a few watts out of the claimed 40+ it can make it probably will sound OK, but how much better/worse and with triode or pentode we may never know. But I like OPTs with wide full power bandwidth.

You can certainly build a test bed and see if it makes power into a
dummy load. If you don't have an audio generator, a dummy load, and at least a simple scope and an accurate AC voltmeter you have no business buying an audio transformer, wouldn't you agree? |

Dunno, I have come across discussions about Lundahl's amorphous C-core...perhaps you are being picky here coz it's a C, or perhaps they are not on the site. Similarly with Magnequest, which is an EI AFAIK. Plenty make small amorphous-cored trannies...you didn't say big ones after all. There are also plenty of suppliers of larger amorphous cores. So they are commercial, mostly R cores, not wound with GOSS. Amorphous toroids don't seem popular. Possibly there is no advantage, as the R-core is just as easy to make with amorphous, and is easier to fill with copper. The only non GOSS types are either mic or line level units. Mu-metal I suppose. cheers, Ian |
