| Does anyone care to ask an amplifier designer a technical question? My door is open. If the capacitance of a cable causes rolloff, is that an artifact?Of course. | |
| A Question About Volume Controls Types Maybe somebody else can tell if there's an advantage with one type of volume control over another?Digitally controlled controls often employ a chip that does the actual volume control change. Because of that the resistive elements often are not to... | |
| Mystery of the whistling amplifier Sounds to me like you have microphonic tubes. Give the tubes a good twack with your index finger and see if they react (whistle changes or goes away temporarily). If they do, replace them. | |
| Clean Power without the drawbacks of Conditioning Filtering. Advice? I don't use power strips. They force you to be using a common power cord with everything plugged into it.I use separate power cords instead, plugged into enough outlets. I had a few extra added! The ROMEX in the wall is better performance than a f... | |
| IN YOUR EXPERIENCE ?? WHAT IS THE QUIETEST 12AX7 TYPE TUBE ??? 6072 ? Spiral Filament Telefunken and Hitachi made the best I've seen. | |
| Zu Audio loading resistors A good bit of amplifier power is just going to be used to heat up those resistors. I can't help thinking there's a better solution. The higher impedance of the speakers is good if you want to keep distortion down, and that's pretty well regardless... | |
| A Question About Volume Controls Types One control is entirely analog and that is what you are adjusting.The other is digitally controlled, and remembers what its setting was last time it was operated. The control itself is simply a counter wheel and can spin as much as you like. When ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Apparently some people just cannot restrain themselves or have difficulty with reading comprehension-Or there might be a third explanation.minimize artifacts occurring from the interconnect cable between the preamp and amp.A second reason is that ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Source output 22R, amp inputs 23k5 or 100K. Adding a preamp with attendant switching, circuitry, noise and additional cables is little more than a subtle tone control. It maybe different, but it may not be better.Some volume controls in DACs are a... | |
| What would be good preamp to run McCormick dna1 The input impedance of the DNA-1 is 100Kohms, which makes it a friendly load for most tube preamps. It only accepts single-ended inputs; @gdnrbob above mentioned our MP-3 (which is a balanced preamp) but I think you could do quite well with our U... | |
| Tubes with Infinity IRS Betas One solution for such an impedance curve is a set of ZEROs (www.zeroimpedance.com) which will put the Betas in the range that most tube amps can handle. | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. why do some amplifier manufactures say to use a preamp between their amplifiers and the streamer when you are only using a streamer and power amp, no vinyl and no other sources. I understand the need for a volume control and to have the impeda... | |
| best place to introduce tubes into circuit What sort of source might you be using? A turntable? | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Well, it turns out that it was my friend Ralph (we have never met, I simply call him my friend) who misspelled Charley's name. He did the measurements of our old M-60 kit for Glass Audio. I met him and hung out back when he was still Avalon Louds... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. I am likely one of a very few designers that actually will repair others equipment. I do this because I like to see others work, how they make things, how their things perform. I have tested over 400 amps and preamps and can tell you all about ... |
