You are correct, the idea is to "hard tie" the tubes together (otherwise you don't get the rigidity... think of a paintbrush where the paint has dried in the bristles... this is what you want). You would need small welds between each tube... a 1 inch...

I woke up this morning to have the brightest thought that my DHT issues are probably caused by how I have wired up the filament transformers. When I ordered all the transformers for this project I gave Lucas of Black Art Automation the design brief ...

Romy, I probably have it wrong, but this "negative impedance" scheme sounds a lot like "Servo". If it's anything like this, then no, i have never seen this applied to mid-bass, but only to "subs". But how would a very small tube amp "control" a mot...

Hi Anthony Agree, waste is waste. The bigger the better. If you care bout sound too, i recommend the RG213 radio cable. Its perfect for that purpose. First, its coaxial which eliminates the inductance. Second its very hard so that during vibration th...

Yeah, so the closeness of the grids results in a higher current gain. So what? What is the relationship between gain and sonics? Are you saying that all high gm tubes sound better than low gm tubes? And does that include 300B ...

Well, the wire paralleling is a common thing. This is where
the idea or Litz wire come from when they use many isolated wires for less them
skin depth. It doe serve theoretical purpose but not always server sonic purpose.

Ok, did today the Red’s tweeters. Got rid of the original Tannoy’s
cable mounting plate and ran my own cable directly from twitter. Drove it with Milq’s full range channel. Used

Paul S,I usually do not compare source components (or amplifiers or cables or etc.) in this fashion, DAC vs DAC, CDT vs CDT etc. unless I feel two (or more) of then (may) be too similar, like Lampizator and AN UK DACs I like. I prefer to focus integr...

Dear Antonio,

An "F" type connector is provided exclusively for use with the optional Sansui FA-7.

[quote user="Romy the Cat"]OK, everything was fine and I might do into the sonic nuances of the PurePower unit. The PurePower drives a lot of switching nose from output. It has the filters but they help only partially. Adding capacitance to the PureP...

It is very uncommon, practically never happens but still very rarely it is possible to talk about sound or playback systems from a prospective of “absolute tone”. Yes, the audio people love to take about tone of their audio but in 99.999% those audio...

I today was abusing my damn Second arm, trying to get my bass back from it. It was not that it had no bass but it was very shallow and very different bass. It had a feeling that it was not from there, it was almost as some kind of time delay in b...

It is know that in addition to basic tastes (I believe bitter, salty, sour, sweet) of the Western culture those “different” Japanese people recognize another taste they call it “Umami”. Umami, if I am not mistaken, is a sense deliciousnes...

With the recent changes on my configuration changes and employing the “End of the Live Phonostage”, in duty I re-thinked my analog playback. I got rid to arms and one deck, changed the mapping between the arms and phonostages and ended up with quite ...

[quote user="manisandher"] And I can indeed replicate this effect... but only with my RME FF800 and not with my Weiss AFI1.

I have found the problem and was able to resolve the noise quandary.
The Lavry ADC has balance analog input and the Sansui has single-ended output. I use my PAD’s Dominus cable with an RCA to XLR adapter. The adaptor was made by BAT and I used it f...

Romy,
I've been storing all my digital music on a computer located fairly far
from the audio system for quite some time now. You've brought up a few
issues that are worth discussing.
1) Storing the digital stream - I assume you mean either (...

Perrew,
LCR is not active at all; it is the very same passive EQ as your RC? I think you a bit confused with terminology. The main logical explanation (there are many of them) is that capacitive filtration is very bad one and need to be minimi...

"... and I do not know if 3A/167M is better than anything else and I do not see why the metal socket is necessarily better then plastic – the socket is not the part of the tube."As you know, the 437A is like an on-steroids ECC83, ALL glass built, no ...
