| Does anyone care to ask an amplifier designer a technical question? My door is open. @roberjerman I have found more data on the 6N30 tube. Same pin-out as 6DJ8 and 6CG7. Plate dissipation 7 watts max. Plate voltage max at 250. Looks like the 6CG7/6FQ7 will work! The Russians copied many of our tubes as did the Chinese. What y... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. For EVERYONE,My new/old/previous technician Ben arrives today and I will be spending most of my time with him and not so much here. I will continue to answer valid questions. We will be making and posting videos at the Berkeley hi fi school site. ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 @ramtubes, Roger, I know you consider the 6DJ8 superior to the 12AX7 for use in a phono stage, but let me ask you this anyway ;-) : how do you feel about substituting a pair of 5751’s in place of a phono amp’s 12AX7’s? I know the 5751 exh... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @krelldreams Roger asked for specs... the only spec I know of is “1.2k” hand written on the bottom of the case. This was only a test anyway since I’d need more than the single input this one provides. I was not aware that Music Reference made p... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @prof Actually, the talk of switchers raises another question I'd like to direct to Robert:I have more than one amp I like to use for my system. It's a minor pain to switch the cables, but it sure would be nice to have a switcher where I coul... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @cardiffkook Roger said.... I put the proper cord on my RM-9 but now people want me to put an IEC on there so they can use theirs. I did opimize but thats not good enough for the PC and fuse people. May I also offer that a captive cord has one le... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bifwynne Not sure what you feel is deficient with the ARC Ref 150SE specs. If you care to elaborate, please doThanks for not getting at me since you own these amps. All I am saying is that Bill was on a mad quest for low distortion and high da... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @pryso That is a simple A-B is not adequate, even though you may find differences. I believe at a minimum you need to have A-B-A. What exactly is A-B-A? we just go back an forth as desired. All connections are cleaned with De-oix from the start. | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @whitestix Roger,I recall you saying at Burning Amp a year ago that you did not like 6SN7 tubes in preamps. I have a preamp that uses these tubes and it is the best I have ever heard in my system. What is the problem with these tubes from a de... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @lemonhaze Hi Roger,Am I glad I found this helpful thread. I have a Mark Levinson 23.5 amp that hums.The hum is loud and stays constant in amplitude regardless of the position of the volume control. I am driving it with an Aikido linestage that ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ieales I'd be curious if trained listeners can reliably detect the sound of the switcher Trained listeners have found the switcher to be transparent. Sounds like in your current setup the listener does not know which he is hearing at the momen... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @mrdecibel Roger, this is a GREAT thread, thank you. I agree that all of the nasty comments and bickering should be kept out of this thread ( as well as all threads ). This thread is about learning, as I see it, and I am learning a great deal ( ma... | |

| Does anyone care to ask an amplifier designer a technical question? My door is open. @teo Some Ignorance is so manifold that it is used to commit to attacks so libelous and underhanded... that the person initiating is practically kicked off a given forum. So obvious to all, that there aren’t even words for it.And then that illite... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @atmasphere A choke is helpful as it can be used to help filter out the 60Hz sawtooth waveform that is part of the rectification process. Ralph, Im sure you meant to say 120 Hz ripple, not 60 Hz unless you are using half wave power supplies.Ch... |
