| Does anyone care to ask an amplifier designer a technical question? My door is open. @prof1 I also wonder how the introduction of a subwoofer alters the load to an amplifier. So say if you have a powered sub and you crossover to the sub from the mains at maybe 80 or 60 Hz. Once one has off-loaded much of the low frequencies t... | |

| Does anyone care to ask an amplifier designer a technical question? My door is open. @stargazer3 For the OP what are the pros and cons in relation to damping for amplifiers; eg Hegel store great reliance for damping in relation to driving difficult speakers. There is no con to high damping if done properly. However more than 20 ... | |

| Does anyone care to ask an amplifier designer a technical question? My door is open. @skiramp Hi there would appreciate some help, I am shipping my Macintosh intergrated amp 200watt plus my def tech bp7000 sc to Thailand to live with me ? Very dodgy mains power !!! I am toying with the idea of ups or stabilizer or whatever , for ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @iamisaf When units are powered on I hear a very mild hum noise from the amplifier unit, if connect amplifier directly to the wall outlet I don't hear any hum noise. If I do the similar setup other side in the basement I don't hear any hum when c... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @analogluvr Over voltage can cause mechanical hum in a transformer Thanks for pointing that out. The flux (and thus mechanical buzz) of a transformer rises sharply at some voltage. That point is up to the designer. I try to get mine still quie... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @tomic601 RM - took a hiatus from the book, restarted on page 59....junction temps....had a bad experience with ON Semiconductor thermal tracs.....I know you are a tube guy, can you comment about the diamond topology ? Not sure what you mean b... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @corby2 Hello, I have a budget system I like. It has a 25 watt Will Vincent Balwin tube amp with Coincident Dynamites. I do not have an audiophile power cord. How much do audiophile power cords help with the amp? I was thinking of getting to Antic... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @almarg Roger, I have a sincere question. What specific technical considerations lead you to be so negative about Ralph’s paradigm paperI hesitate to answer your question for the fire that will reign down on me. But this is the last I will deal w... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. I want to end this amplifier pissing contest. This is not the purpose of this thread. If someone wants to make amplifiers out of the accepted normal standards why would he be coming here? We are discussing normal amplifiers not outliers.99% of s... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @utrak I’ve got a question for the tube amp designers. How much of a difference does the power transformer make in a tube amp design? Is the output transformer more critical or the power transformer or both? I’ve read that the output transformer ... | |
| RMS Power? @imhififan Thanks for the nice words, Roger and ALI wish kijanik would join us in laying to rest this matter of three misplaced letters. It appears that three letters misplaced caused all the fuss.I will soon post a paper on my experience of the... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @atmasphere Our MP-3 preamp is based on the first balanced preamp circuit ever sold to high end audio (our MP-1). It has a direct-coupled output (despite being a tube preamp) and has bandwidth to about 400KHz. Hum, This is a bit self promoting ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @atmasphere But here's the kicker: This thread was put up as a promotional device. You can tell because the manufacturer is talking about his products, often more than once in many of his posts. This is against the Audiogon rules, but because ... |
