Que pre estás usando, me suena más a la ecualización RIAA

Te quedaron espectaculares las cajas, da gusto ver ese trabajo,

[/quote] Jajá, nos fuimos de OT, perdón. Es otro amplificador valvular a propósito de una posible nueva configuración de tubos que se mencionó y para allá derivó la cosa. [/quote] Está bien, me interesa la modificación de Carver al Bell, tengo un Bell Carrillon 6060, me interesa muchisimo, si pueden poner datos, se agradece.

Del technics o de que estamos hablando?

Cuenta de la restauración del amplificador si la vas hacer, si ya está restaurado, si podés poner fotos de la misma sería buenisimo

El reconocimiento a Stu Hageman, que te parece? , mucho jugo este post

Justamente en la venta de ebay de ese amplificador, Bob Carver señalaba y agradecía a Williamson, Haffler, y especialmente a Stu Hegemann, diseñador del Citation ll el diseño Push Pull de los 50, busco la cita y la transcribo. Tubos miniaturas, pin 7 de los 50. [color=black][font=Arial][size=2]It was a hot mid-summer's night and I was in Chicago at the consumer electronics show.[/size][/font][/color][font=Arial][size=2] [/size][/font][color=black][font=Arial][size=2]I was in my booth pitching my wares, a new amp and preamp, and it was hot inside. Not the amplifier, but the convention floor, and I was getting thirsty. I wanted something cold to drink, so I decided to sneak away from my booth for a moment to get a coke. As I was sneaking, a colleague happened to walk by and said, " Hey Bob, have you seen Stu Hegeman's new preamp?"[/size][/font][/color][font=Arial][size=2] [/size][/font][color=black][font=Arial][size=2]I found myself getting excited, as Stewart Hegeman, the master designer of so many classic vacuum tube amplifiers and my very own hero, was here! Stu Hegeman was a true genius, having designed the Citation I, II, probably the III and countless other amplifiers for Sidney Harmon and forLafayette.[/size][/font][/color][font=Arial][size=2][/size][/font] [font=Arial][size=2] [/size][/font] [color=black][font=Arial][size=2] I found him in his booth; we began talking about preamps and amplifiers, ultimately leading to a quiet corner in a close-by restaurant. Very close, as it was part of the convention itself. I finally got my coke. I could not believe I was in the presence of THE Stewart Hegeman, and he was talking to ME! We talked and talked about big solid state amps, tube preamps, solid state preamps, loudspeakers, ionic tweeters, recording lathes and finally tube power amps. And what a scientific talk it was! As the hours went by, he admitted to having been caught up in the ultra-linear fad of his day, that it was the biggest blunder of his career, and he did it only once and would NEVER design an amp with an ultra-linear output stage ever again. [/size][/font][/color][font=Arial][size=2] [/size][/font][color=black][font=Arial][size=2]And he didn't. The Citation V was pure pentode, as was the subsequent Lafayette 550 and everything else he designed from then on. I asked why. He explained that when the plate pulls the top of the output transformer winding towards ground, the ultra-linear tap pushes the screen grid so low that it renders the tube unable to drive difficult loads. In addition, he pointed out that the normal idle potential on the screen grid regularly exceeded a safe voltage, often causing output tubes to blow up. The tube manufacturers hated it, but had to go along or lose market share, and so changed the specification for screen voltage in order to allow ultra-linear output stages. I can’t help but wonder if they REALLY changed the tube design, or simply changed the screen voltage specification. This conversation led to me confessing that I had always wanted to build a big tube amp that was painted the same color as my first car, a '49 metallic burgundy Mercury automobile. So I started on it. And here it is![/size][/font][/color]

Por supuesto que es válida y entendible la opinión del forero y en muchos aspectos la comparto frente a un amplificador vintage,no me referí peyorativamente al expresar negativo, el amor por lo vintage pasa por algo nostálgico y cierto románticismo, creo.

[/quote] No creo que todo este hecho o dicho en valvulares...siempre aparece algo nuevo [/quote] Decime que circuito nuevo hay? en valvulares, algún diseño nuevo, por favor

A mi me gusta el vintage, tengo varios amplificadores vintage, y te felicito por ese amplificador, creo que el comentario negativo te lo hizo otro miembro, suerte

La pregunta no iba dirigida a ti, era para el creador del post, ya vi que tiene un Marantz 2216, de acuerdo?

Si quieres probar ribbon tweeter, en parts express hay varios modelos que te pueden servir para probar sin necesidad de comprar un sistema completo [url="http://www.parts-express.com/wizards/searchResults.cfm?srchExt=CAT&srchCat=567"]http://www.parts-express.com/wizards/searchResults.cfm?srchExt=CAT&srchCat=567[/url]

OK, ahora sí, me gusta más el SB-10000, es perfecto para mi configuración (para tri-amplificar) y tengo algo muy parecido. Sobre gustos no hay disgustos

[font="arial, verdana, tahoma, sans-serif"][size="2"]El voltaje de placa 400v, resistencia cátodo 390 ohms, y un diodo a la grilla del tubo final y el diodo del transformador es una protección para los parlantes .

doble post[img]http://www.hifichile.cl/public/style_emoticons/default/sorry.gif[/img]

y que pre de phono pensás usar?

RIAA = Record Industry Assoccciation of America Equalization Qué es, querés saberlo, bueno lee este link [url="http://www.duiops.net/hifi/enciclopedia/riaa.htm"]http://www.duiops.net/hifi/enciclopedia/riaa.htm[/url]

Escultor, estoy hablando del pre de phono con ecualización RIAA, cartucho MC o MM
