| Does anyone care to ask an amplifier designer a technical question? My door is open. @ atmasphereSo what is the cutting curve? Can you show us please? | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Hey Roj, Its Verastarr Mikey.. Id like to know when we roll tubes and hear differences that are so different and unique even when its the same exact tube type, how and what exactly are we hearing ? Lets take 2 6sn7GT for instance, that for the pur... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @atmasphere Try telling the manufacturers of cutter electronics that. How about telling us about the cutting process? The range of constant velocity cutting and range of constant amplitude cutting. I was not discussing cutting, but you appear ... | |
| MAC Autoformers? @toshko1 Hello, I found the thread and read it very carefully. Presently I am reverse engineering this type of block scheme of power amp.Thanks for reading the thread carefully, however there is not enough information to calculate the transform... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 Roger, could it be the old 1kHz frequency was chosen in relation to the RIAA equalization curves? That would have been a better choice resulting in 500 Hz for the low hinge and 2 Khz for the high. I would prefer a larger gap as stated e... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Concerning tone controls, thank you,,, very good to know It appears in design the good ideas are only done briefly by the few yet the bad ideas are done by the many and go on forever.I think the choice of a single hinge point was the biggest mista... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. ON TONE CONTROLSThe typical bass control has a hinge point at 1,000 cycles, much too high. In my system I use the Subwoofer level control (100 Hz and below) to set the bass to the right level without making vocals muddy like most tone controls do.... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @jyprez yes, I would be happy to pay for coursework on the subject. What do you offer? Currrently basic amplifier design. Are you local to Richmond. CA 94806? | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @c1ferrari Re: BeveridgeHi, Roger,You'd worked on the Bev DD amps for my Model II's when you were situated in Santa Barbara. Unfortunately, Rick was unable to complete the restoration process and my panels require attention. Can you assist?T... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @radiointerference Hello Roger, thanks again for this opportunity seeing you worked for Harold Beveridge , I have two questions, 1). I have a pair of Beveridge 2SW's with a panel that has gone south. I am looking to make a jig to tension the myl... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @michaellent I want to learn about amplifiers Hi. What would you like about amplifiers? They are my favorite subject and life's work. Did you check out the YouTube videos and Burning Amp?Realizing early on that the applications in the RCA and oth... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. the velocity of propagation of the signal (versus the velocity of the actual electrons) is determined by the dielectric or insulation material that the electromagnetic wave is predominantly traveling through. I would like to see some proof of t... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. http://www.audiosystemsgroup.com/TransLines-LowFreq.pdfThe last paragraph of this 3 page paper dealing with transmission lines admits that we are not in transmission line territory at audio frequencies.. Electrical Wavelength at Audio Frequen... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @rollintubes I am sold on tubes for analogue audio but am confused by all of the information on power. I see from many posts that tube power need not be very high or as high as the speaker manufacturer claims as a requirement, i.e. a 200 WPC SS ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Roger, Thanks for this great thread! It is one of the best threads I have ever read on this website! Your time educating us non-technical prople is greatly appreciated. I still own the original Beveridge Model 2׳s and have a couple qu... |
