Adjusting tube bias...
Hi all. I’m hoping that someone reading this thread will be able to help me. I am also not new to tube amp use, but most of the tube amps I’ve had have had a built-in method to test bias. I bought a 1961 HH Scott LK-150, which has a bias meter on ...

Hello. I agree this is a very generous offer! I’d like to take advantage of it ;). I have some components on cutting boards, and have always wanted to try the Mapleshade platforms, but found the price beyond what I was comfortable with for an expe... 
Does removing anti-skating really improve sound?
Lewm, I know the numbered value dials you refer to (I’m kinda *from* the good old days ;) ). The Rega arm has a few detents in the antiskate lever which represent 0.5,1.0,1.5,2.0 (iirc), and the manual suggests choosing the value that represents y... 
Does removing anti-skating really improve sound?
Jack, it is my understanding that the skating force is not equal across the entire stylus path from lead in to lead out... plus, even if one were to consider doing what you suggest, any sprung table, or any unipivot arm, would use the same forces ... 
Does removing anti-skating really improve sound?
 As others have pointed out, there are many different combinations of factors that contribute to the skating effect in each set up. I have a VPI Scoutmaster Signature, which included an antiskate device. I have tried it with and without a number o... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
@ramtubes.    It is very likely that what I’m hearing with this preamp vs passive thing is a less than perfect passive, against preamp distortions which “smooth” the sound. I’d like to know more about your suggested solution to this issue, but con...

What I’m hearing is a thinning of the midbass range. The lower bass is coming through. There is also the etched character I hear in the higher frequency range. These are slight, but obvious changes in the sound which, together, render the music “l...

Gentlemen, thank you for your advice. I actually never intended for either the Axiom passive, or the little Mani to take up residence in my main system, however I decided to try them, which lead to my interest in replacing my preamplifier. What st...

@ieales. Thanks for the link.. I’ll check it out. My comment regarding the phono preamp with aux inputs and level control was made selfishly because I am very much interested in outstanding LP playback, and only listen to my digital sources casual...

Sorry, I had mentioned my sources in a previous post, but this thread has many, many posts by many people! I primarily listen to LPs, but I do have a DAC (Cambridge DacMagic Plus), and an Audioquest Beetle to stream Spotify over Bluetooth. I initi...

Thanks George. I like the idea of a passive control device, and I’m trying to learn about the system matching aspect so I can try an appropriate unit. I did appreciate the clarity, but was distracted by what I’ll call an overly etched, and leaner ...

@ramtubes. I measured the impedance of my passive across the input to the output as you requested. It measures 1.21kohm, which is as written on the bottom of the case. I opened the case and found an Alps volume pot, two resistors, and wiring. I pl...

@atmasphere. Great comment (on hearing)! I believe our hearing mechanism is somewhat of a “moving target”, so to speak. I’ve wondered why sometimes music through my system sounds great to me, and other times, not as good. Even when playing the sam...

@ramtubes. You mentioned, that in the RM 9, two KT120 or KT150 output tubes could be substituted for four EL34s in each channel. Is there an advantage to using fewer higher output tubes as opposed to using double the number of lower output power t...
