| Does anyone care to ask an amplifier designer a technical question? My door is open. * Discussion on diode transients and measurement thereof here: https://electronics.stackexchange.com/questions/323507/bridge-rectifier-4-diodes-vs-single-chip Not much meat or it sounds. I didnt read the whole thimg. In my RM-5 preamp I found ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @jafox Thank you for the responses above. The preamp is Aria WV5, the last design by Michael Elliot of Counterpoint 10 years ago. The last thing I want to do is to put anything else in the line such as a transformer.My experience has been that the... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. daveyf first the swapped polarity from amp to speaker does no harm and most will not hear any difference as long as the swap is the same on both sides. All you have done is invert absolute phase which has been a point of contention for many yea... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @prof I could really use some help betting a better grasp of amplifier/speaker interaction. Specifically, in what sense a speaker is "easy to drive" for an amplifier.This seems to generally relate to two parameters:1. Speaker sensitivity2. Speaker... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ atmasphereIn one post Roger says it doesn’t make much difference, OTOH in the very same post describes the power cords that he made up special and how anyone can do it. I have to assume that he felt it was worth doing. Ralph, what is OTOH mean? ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @fleschler ramtubes - So, you don't believe power cables make a difference other than connectors and isolation transformers are worthless? Is that correct? Do I detect a little nudge there? I think isolation transformers are great when needed... | |
| 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. @khiak Can changing the power cord to the amp changes the musicality of sound at the speakers. Some think so. | |
| 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. @testpilot How do you block DC.Connect two diodes back to back in parallel and insert in hot lead of power cord. | |
| 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... |
