Raal Ribbon Headphones - SRH1A
Not surprising with blown fuses because 1.6 A is adapted for 230V. I recently got an amp for 230 V use in Europe and the text on the back of the amp is updated with: 115V/3A * 230V/1.6A Nothing special with that, this is the case for all equipment . If you use half the voltage then the current...- Anders

The Leben CS300XS Thread
It's very easy if you hear two tones after another but more difficult with a single tone. I have a CD with test tones (sinus tones) for speakers and listened to 100 and 50 Hz. I have another amp for the speakers and compared not directly but the slight hum I can hear from Leben should be 50 Hz...- Anders

It certainly has a higher noise floor than modern SS amps.- Anders

The Leben CS300XS Thread
Quote: It you really want to destroy your ears you could try with 20 ohm resistors for higher output! Congratulations to the improvements! I didn't say that a choke removes humming and only asked my tube guru about it and he said that it is a good idea and it reduces noise. I...- Anders

Looks like Duelund capacitors, the big ones in the picture are very expensive!- Anders

The Leben CS300XS Thread
Thanks Raaf and BugleBoy! Looking closer at the picture I can see that it is a plate and not a box. I thought that was some goodie in the box that you only get with the X model. It is not so but there are still a few components of higher quality in the X model.- Anders

The Leben CS300XS Thread
Quote: I assumed it was a choke because it has been said that there is a choke in the CS300X model and there is no such box in the CS300. In the CS300 there is no box as in the picture I published and neither the resistors on you picture. Is the box just a cover for the resistors or...- Anders

The Leben CS300XS Thread
The choke on the CS-300X is located in the upper section of the amplifier, between the power supply and the transformers. I don't know how it is connected and the circuit, but it is probably wired differently than Raaf's choke.- Anders

The Leben CS300XS Thread
I spoke with my tube amp guru today, he has a long experience of designing and repairing tube amps. He didn't believe that driving HE-6 direct from the speaker outputs would damage the amplifier, but could not give a guarantee. He said that it is safe with a parallel resistor and also could be...- Anders

The Leben CS300XS Thread
I also believe that the distortion depends on the power demand of HE-6. Please tell us what Leben say about driving headphones on the speaker outputs. It has been reported earlier that the power is enough for HE-6 but the impedance mismatch could possibly damage the transformers. That is...- Anders

The Leben CS300XS Thread
There are certainly better tubes than Golden Dragon but you should not get different results with other tubes regarding output and distortion, or only marginally. 5751 has a lower gain than ECC83 but the difference is not great. It is not sure that the amplification will be lower with 5751...- Anders

The Leben CS300XS Thread
Yes, that is obvious but it is total sound quality when playing music that counts. Those quiet listening sessions seem mostly to make people nervous, especially those that are not used to the noise level of tubes and vinyl and using SS and digital as reference. Leben is either not the most quiet...- Anders

Headamp Blue Hawaii Special Edition
007t has a switch but input 2 works both as RCA and XLR and you must set the switch after what you use. 007t ii has three inputs and input three is only balanced according to the picture. This is a change that is more user friendly because many users have difficulty understanding the thinking...- Anders
