Looking for tube amp suggestions
Zu had our S-30 for a long time- as we did the Druids. The Druids and the S-30 are an excellent combination and you get about 40 watts per channel, so it would be impossible to overload the amp in your room. You can remove power tubes from our amp... 
TriPlanar Tips
Hi Lew, I run the Transfiguration Orpheus at home. Here at the shop we use the ZYX Universe and the Anti-skate weight is set at the absolute minimum. 
TriPlanar Tips
I like the arm because it works- one of the very few that does. I like Tri because he can deliver.I don't even have the AS weight mounted on my arm. It tracks anything I can throw at it effortlessly: Black Sabbath Paranoid, Decca's Ring Cycle cond... 
Can You Live With Crackling & Popping Noise?
I don't mind a few ticks and pops- they tend to exist in the speaker for the most part. The artifacts of digital tend to exist in the music itself. Fortunately digital has gotten a lot better over the years. The advent of 88.2KHz 24 bit recording ... 
TriPlanar Tips
I spoke to Tri about what was the right Anti-Skate setting on the arm and his response is that there is no standard, no means of knowing what the right setting without audition, and that different cartridges seemed to have vastly different setting... 
Vibrating Woofer, old tubes?
Dfelkai, most shops in the US will charge about $75-$80.00 per hour. That allows them to pay the technician and their overhead. Filter caps do not take a long time to change, and this is entirely off the top of my head, so unless there is somethin... 
Vibrating Woofer, old tubes?
You have bad filter capacitors in the power supply. This condition is called 'motorboating' and can be affected by temperature and the length of time that the unit is one.It is something that needs service! I would not operate this unit until this... 
Suitable tube preamp for pass labs x250
Tvad, the output impedance of the MP-1 is closer to 30 ohms, not 350. Its bandwidth is unaffected by load. 
To bias or not to bias
If you are adjusting the bias more than once every 6 months I would regard that as 'tweaky':) Seriously, the tubes should be able to hold up that long without adjustment. 
Can You Live With Crackling & Popping Noise?
One way that is not obvious to reduce ticks and pops is to use a tube phono section that uses passive RIAA equalization. Transistor units will often over-react to ticks and pops as most of them use loop feedback for the EQ. Loop feedback enhances ... 
The Richard Clark "all amps sounds the same" test
Lightminer, here is something else to consider:http://www.atma-sphere.com/papers/paradigm_paper2.htmlIOW, a speaker that is designed for transistors may not work with tubes without tonal anomalies, and I for one (if doing the test) would insist on... 
Why manufactures don´t burn in their amps and ...
Magfan and Al, you want to keep in mind that the power surges are the ones where the power supply rectifiers commutate (that is to say they turn off and on) at the peaks of the AC waveform. As soon as the AC waveform drops below the value where th... 
Why manufactures don´t burn in their amps and ...
A voltage drop on the power cord is caused by two things: the gauge of the wire and the quality of the connections.If your power cord is heating up at the connectors, here is an example of why things like the Porterport or medical-grade connectors... 
Does Pass Aleph 3 heat up the room like tube amp?
my experience has been that if you choose a system based on the heat that it makes (or doesn't), the sound will reflect that.If the heat issue is really that bad, look into class D amps.There are probably other alternatives though. You could vent ... 
Why manufactures don´t burn in their amps and ...
For those who wonder how a power cord can make a difference, consider this: an amplifier has a power transformer, rectifiers and filter capacitors in its power supply. Normally, the filter caps are charged by the rectifiers as the transformer make...
