Erik Mandaville Posted September 10, 2004 Share Posted September 10, 2004 c'mon, Craig! What's the key word to the kind of amplifier this is?! It's in the description. Quote Link to comment Share on other sites More sharing options...
NOSValves Posted September 10, 2004 Author Share Posted September 10, 2004 Sunny, What section of AA is this thread in. I just did some quick searching over there and I can't find a thread God I hate that ancient forum software they use ! Craig Quote Link to comment Share on other sites More sharing options...
Guy Landau Posted September 10, 2004 Share Posted September 10, 2004 I think that the value of thess caps should be subjective. For me, They're worth every penny. I've had $300 worth of BG caps in a $1k VTL preamp and the improvement was huge. Better deffinition, faster and tighter bass. The improvement (again, subjective) was bigger than a $300 worth of NOS tubes made in the same preamp (before replacing the standard electrolythics). The biggest drawbacks are: their high cost, very long break-in period and the shift in sound during the break-in. I do have them in my Loesch preamp's, power supply and again they made an improvement. Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted September 10, 2004 Share Posted September 10, 2004 Craig: This is just for fun! Won't you hazard a guess? It's kind of important to what is actually going on in the circuit! Ok....I'll give you a hint: it's not a conventional SET amp for a couple of reasons. Quote Link to comment Share on other sites More sharing options...

Different strokes for different folks! Klipsch out. Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted September 10, 2004 Share Posted September 10, 2004 Hi, Edmond: ...not quite, But good effort! Craig: This is a really promising looking tube, by the way, and the application is pretty neat! Quote Link to comment Share on other sites More sharing options...
sunnysal Posted September 10, 2004 Share Posted September 10, 2004 craig I am pretty sure it was in "general"...I have to look again, might be kinda old, a week or so...martin colloms writes for HiFi News in the UK, a publication I really like, he did extensive testing of the BG caps....regards, tony Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted September 10, 2004 Share Posted September 10, 2004 Ok, ok.....I won't bother with this anymore. It was just for some fun as a way to talk about the general circuit design of your new amp. There are some special things going on in there. Seek, and you'll find if you want to!

NOSValves Posted September 10, 2004 Author Share Posted September 10, 2004 Eric, I don't need to guess I know its not conventional SET and is exactly why I bought it. I have now heard a number of conventional SET amps as you call them and I personally do not care for them. I hope this indeed is different. Feedback is not a bad thing !

Whether you think there worth the money or not is your business just like any customer of mine that may want them I have no problem using them but IMHO they are a ripp off.

Guy Landau Posted September 10, 2004 Share Posted September 10, 2004 What exactly makes them more ripp off than Auricaps or Hovlands for example? When comparing same value Auricap to 716P Orange Drop (the expensive one ) the ratio is 10:1. Where does the big difference come from?

Deang Posted September 10, 2004 Share Posted September 10, 2004 Craig -- you said you cut some open and compared them to aluminum electrolytics, and said they were the same. I was only pointing out that they couldn't be exactly the same. Construction is quite different, as Rick noticed and pointed out. I never said they were better, or that the claims were legit -- only that they were built weird and had broken up pieces of pencil in them. Now, as far as specifications go -- they have no equal (electrolytics). I have no idea whether they make the sound better or not, though there sure are a lot of folks who say they do. At any rate, I don't think it would cost $800 to replace my power supply caps with the BGs. You're not daring me are you? Edmond -- though it's not the norm these days to implement feedback in SET amps to lower distortion, it's not completely unheard of either -- I believe the $75,000 Tenors have more feedback than my QUADs.

Erik Mandaville Posted September 10, 2004 Share Posted September 10, 2004 The term 'feedback' is being tossed around sort of loosely, here..... Quote Link to comment Share on other sites More sharing options...
Deang Posted September 10, 2004 Share Posted September 10, 2004 You didn't -- I believe it was just a general comment in response to Jazman's observation. Quote Link to comment Share on other sites More sharing options...
Deang Posted September 10, 2004 Share Posted September 10, 2004 Probably because I don't know crap about amps. Hey, I know there's global and local feedback -- but I have no idea what the difference is!! Quote Link to comment Share on other sites More sharing options...

The company owners are lining there pockets with the black magic money. Auricap would be the worst offender they raised there prices this year to near Hovlands film and foil prices for a metalized cap I quit buying them right then and there. At least the Hovlands are indeed a more expensive design to produce. The absolute worst offender in the coupling cap business is Jensen PIO's oldest out dated technology reaping in the most bucks doesn't take much common sense to realize the black magic pricing structure. ONCE AGAIN I AM NOT SAYING THESE PRODUCTS ARE OF BAD QUALITY !! I'm saying there not a value or worth the prices they charge. I bet a dime to a dollar the mark up on Blackgates is near tenfold if not more. I have a funny thing about me I like to feel something when I get screwed.

NOSValves Posted September 10, 2004 Author Share Posted September 10, 2004 Eirc, I just wrote a long reply to your magic word question and this darn forum crashed Grrrrrrrrrr The short of it parafeed chokes grid choke on a permalloy core to allow sourcing of positive grid current on peaks little local negative feedback In a way this is a dual mono design since the channels PS are all isolated via the chokes throughout. And on and on I just hope the amp sound completely different then the many SET amps I have heard to date. Craig Quote Link to comment Share on other sites More sharing options...
Wardsweb Posted September 10, 2004 Share Posted September 10, 2004 The amp is coming from me. The builder is a very good friend of mine and kind of my DIY tube mentor. I built my 2A3 SET using a design I got from John. The man is phenominal when it comes to audio. As for the "Iron Giant", it is a sweet amp. Not only do you get that velvet SET tube sound, but with some guts. It has a strong bottom end and still mantains very good imaging. I believe in the amp enough to not have any problems selling it to a friend. That and he got a KILLER deal on it. He paid less than the cost of the iron alone. Enjoy Craig, I know you will be impressed. You should try pushing your La Scala's with it. I think you will be amazed. SET's and horns were made for each other.
