I am not sure what rectifier the 2A3 SET uses. Mine uses the GZ37. The best regarded is usually the Mullard NOS. I have used that for years.
Recently I was on the kick of listening to the vibration of tubes and I came across a dirt cheap tube fr...

[quote user="jessie.dazzle"]I feel a driver needs to be somewhat hard-mounted to the enclosure. Cork gives the right sort of balance between hard-mounting and floating, while still sealing.[/quote]It's all about finding the balance point between the ...

Romy,
I assume you plan to use one of these as the driver tube. Do you distinguish any difference in the sound between the two tubes? I am curious as I have been looking over a big pile of them and they respond quite differently regarding vibrat...

[quote user="floobydust"]I do agree that the internal structure makes a big difference... but, if the tube specs properly and has adequate immunity to mechanical induced interference, then you should not be able to discern any major difference in sou...

I totally am a believer that the construction of a tube determines how it will sound. This makes perfect sense when you consider the tube is relies on the changing flux of electrons in a vacuum. It is easier at least for me to visualize this as a ph...
|
Just some additional thoughts on the new generation of 2A3 tubes. The only ones I would seriously consider are the Kron Enterprises, the Sophia Electric, and the Emission Labs tubes. If I did not hear these side by side over an extended period of ti...

[quote user="Romy the Cat"]The first thing first I think that your fear that your “midrange might have ideal frequency response” is not a motivation to change anything. Are you concern about frequency response or about the well-identified subjective ...

The EdgarHorn Titan is a very well made speaker, but I have identified in it a limitation in the midrange where the frequency response may not be ideal. This will become clear after I have analyzed the speakers with RTA.
Thinking ahead, I want to...

[quote user="Tuga"]Joe, Don't get me wrong, I really enjoy a good pizza. Unfortunately I won't find one in a Pizzahut. "That" man's 2 for 1 pleasure says a lot about his evaluating capabilities... I also enjoy several different kinds of music, mostly...

[quote user="tuga"]If you have a midrange driver you can try that for yourself.[/quote]In this case the lack of "full-range" audio is so glaring it overwhelms any advantage of the point source, I think.

[quote user="Romy the Cat"]The line-level crossovers work against fixed impedance and therefore the crossover point and the time alignment does not fluctuate along with reactance of the drivers.[/quote]Okay, maybe this is a dumb question, but why wou...

Having listened for a while with the tubes, I have come to some conclusions. The three tubes I have seriously listened to are: Kron, Sophia, and Emission Labs. All the tubes are much better than any other modern 2A3 tubes I have tried. I felt my in...
