I am interested in Graham and others ideas on this. I might try to build one but I would like to read and learn more about this classic design. |

Good places to learn...
The link in my original post above (http://www.tcaas.btinternet.co.uk/jlh1969.pdf) and Elliott Sound Products page http://sound.westhost.com/jll_hood.htm where Rod Elliott chips in with further insights into how it works. Even though ESP may be considered competition I must admit the chap is quite an expert, and although I do beg to differ on some of his observations, I'm more than happy with how he describes the "Hood" here. I took the liberty of using an image link from his website (picture below) which shows the basis of the design... And will scribble out my test circuit which used smaller transistors, and upload it as soon as I can. This topic is more for discussion and experiment than for me to offer a kit or do anything equally as commercial (and in lieu to a degree of not getting anywhere with the mag yet...) |

Thank you very much, Graham, these resources are spot on. I can only comment on my personal interest in this, but I would like to know more about your take on the JLH and adapting the NE5534's topology. How about other members of the forum? Edited by Fatmangolf - 19 Aug 2010 at 10:06am |
