 Miguel too as he has been hearing and hearing at many meets until probably he hears babes calling out sweetly in those he heard as well.   |

 That's a lot of whack. With my vol pot then, it must be the way it's set up so I can use the whole travel perhaps? I don't go beyond 1 o clock with the K601 and never really tried it but I guess the volume will keep going then, rather than what a lot of amps do.... Their real maximum is often round about 2 o clock and then turning up adds nothing. I guess the V2 will keep going - mind you, I don't want to deafen myself. Of all the amps I've tried Chong, this one has always remained as my favourite. It's a real workhorse and is full of character. It makes many SS amps seem like you're in a white walled hospital!! Like that thin soup you can get with nothing in it - water and a few bits.  If you reverse the gain mod to stock it will blow your ears off at 1pm  Maybe time for a valve change Ian, have you used it a lot since fitting them? I use it every day, Mike. Love it to bits!! That accounts for it. I didn't even think about the gain being modded - so that's why it doesn't go into distortion or anything nasty a long way up. In fact it has a lot more!!! Chong, just because of my job, doesn't make me a good hi fi guy!! I just like what I like but I'll tell; you what, if you don't like the V2, there'll be people after it like whippets!!! Mine is so quiet as well when it's running. No noise whatsoever. Guys at work talk of noisy valves etc., I get none of that. It's clean as a whistle. It's the one I always return to. (Rather like Sennheiser headphones actually!!) |

Chong, Don't put the 6N1P-EB anywhere near the V2... they have been responsible for a lot of fry ups, just don't go there  I'll PM you regarding the 6H23N-EB. My stock is genuine NOS, they have never been out of their cartons and the rusty staples will prove that!! I'm fortunate enough to have bought in at the right time from the "right" source... some of those things described as "NOS" are actually Nasty Old Shit old "used" valves which are being punted out as new old stock, I couldn't sleep at night sending that garbage out to people. I even match the valves in their cartons so they arrive intact "with" rusty staples I use socket extensions and plug them into the Tube Imp with their cartons on.... quite time consuming doing a batch of 100 (for example) and matching pairs but, fortunately, they are all VERY close anyway so I am never left with odd ones.... fantastic valves, beautifully built and deserved of their military specification.... Russia were crap at making cartons but their valves are friggin' bullet proof! Try doing the same with USA built JAN 6922... you will start tearing your hair out matching a box of 100... they're all OVER the place! They also have a tendancy to be microphonic so you probably get 60 out of a batch of 100 that are good for audio purposes. The absolute worst EVER have to be the Chinese 6N11J... the "J" stands for military quality, they are equivalent to the E88CC / 6922 / 6H23N.... Don't get me wrong, they sound nice enough but try matching a pair.... they're off the map! Precision matched pairs are not even necessary in the V2 but I always like to sell them as close to each other as possible.... I'll PM you re: the 6H23N-EB Chong as you seem to want to discuss a "discount" price... we can haggle via PM You lend me your wife for a week and I'll knock 50% off the price type of thing.... yeh, haggling is good IF you operate out of a suitcase in some low end market.... I was going to send you a pair FREE but seeing as you are looking to haggle we can take this to PM.... my starting price is £395 per matched pair (shipped) I will throw in a matched set of fingerprints to PROVE I have touched them... for an extra £100 I'll even sign the cartons.... No no... seriously, will send you a PM now Mike. |

I was going to send you a pair FREE but seeing as you are looking to haggle we can take this to PM.... my starting price is �395 per matched pair (shipped) I will throw in a matched set of fingerprints to PROVE I have touched them... for an extra �100 I'll even sign the cartons.... No no... seriously, will send you a PM now Mike. Heh, heh, heh, I'm not going to price haggle you. I'm going to ask you buy one at almost 0 pound and get all free + air shipped! Anyway, on a serious note, PM already sent. Regarding the 6N1P-EB, it should still be not a problem as I will very much up the tempo in the PS department wrt to Schottky diodes and traffo as well as any resistors to at least more than 3A. Just need time to figure that out. But obvioulsy it will be in an Americana freewheeling hifi way that's in me to "blow to smithereen" any hifi related with regards to sound. Not technical, btw, but SOUND QUALITY. Well, as usual, Frans and Alex may not agreed on this.  |

Thank God it's not the tubes in my V2 that are giving way but the bloody socket and pin oxides giving the crackling problem. After I swapped the 2 tubes around and reinserted them, all crackling problems gone. Mike, you are right about the oxides. Now I can appreciate fully the power and sound of the V2. It's powerful and I listen only at 9 o'clock for a 32 ohms HP. Now eerily super queit too for the V2 like it is a transistor amp even with volume control all the way at max. No tube hiss or whatsoever and Frans and Alex will want to have us believe that tube will give bad S/N. But we audiofools are asking for hear to believe SOUND QUALITY and NOT TECHNICAL SPECS QUALITY. Obviously your new tubes will up the tempo of the V2 sound department into stratosphere heaven and Frans and Alex will have us to believe it will sound no different as it's the 6922 equivalent in technical matter. Also, is the V2 known to give high amount of DC offset. I don't have the time to measure it yet and I don't want to damage any expensive HPs that possibly can come my way. Still evaluating the sound and no full comments yet. But sound is very good and not only good. More wholesome like Live but not Live obviously. Bye, need to prepare to go for the morning rat race again. |

That doesn't mean it's powerful. It just means it has excessive gain. You can rectify that with my posted modification. Yes, a valve amp mod from a SS person!  |

Not technical, btw, but SOUND QUALITY. Well, as usual, Frans and Alex may not agreed on this. After some further thoughts during the rat race on the road , I think this is not such a good idea after all to put in 6N1P-EB even if it does sound better. This is because the MF PCB is quite junk by my PCB years at PCBA plants std and this will create more lifted pads on it's on due to more heat generated! Also, the HA is enclosed with no ventilation and there will definitely be a potential pressure cooker there unless you drill ventialtion holes on the casing. Nope, not for me as I prefer the original look. Also, who will buy a freak when I don't love it any more? Anyway, this is most unlikely until I hear better ones. I hope I will still stay married to this like Ian and Miguel.  So guys, if you are even thinking of it, forget about 6N1P-EB. Still up the tempo in the PS and use the 6H23N-EB/VR will be good enough. Ah, this is only where technical reasoning helps. |

Oh, I don't want to adjust anything as when it comes to 600 ohms HP, the same cycle goes again. Original present setting is just fine. Hmm, maybe a gain switch will be nice. So any high voltage involved for that switching? If have, then forget about it. Let me think about it. |

Er, I mean any high voltage across that resistor? If put in a switch there, if with high voltage, will be a zapper for me and anybody touching it when on if the swtich is put outside the V2. |

Use high resistance reed relays , controlled by a front panel switch. You don't want long leads from feedback compnents. |

What a wuss ! ;D It's only 4V higher than the 15W Class A on the +VE rail, and 1V higher on the -VE rail. These are TOY valve amplifiers, not the real valve amplifiers of yesteryear with HT of +250V or nuch higher. |

No need to make things so complicated with a relay. KISS, man! ;D |

Chong
Believe what you want, but a good SS amplifier can be more than 20dB quieter.Just look in a good sound editing program at Chesky Audiophile CDs created using valve gear, such as a Rebecca Pigeon anniversary release.

Oh, I don't believe, I hear. It's super quiet for the V2. I think Ian and Miguel can also confirm it. It's not like those tube phono stage. It sounds like a SS HA in terms of noise in the V2. I'm not kidding. It's the truth and nothing but the truth. Get hold of a well maintained V2 to hear it for yourself. |

Let me see how short I can get for the wires if ever I want to implement this. If too troublesome and it does oscillate, I will leave it as it is in the original state as I actually don't have any problem regarding gain at this moment. Just something to have and not something must have. |

Why on earth would I want to listen to any amplifier with artificial warmth ? I have been there, done that around 30 years ago with Mosfet power amplifiers with a FET input stage. In any case it's not a proper valve amplifier, it's more than half solid state.It's not as quiet as a good SS amplifier, no matter what you may wish to believe . Measurements will show that. Neither does it have a greatly extended HF response, or anywhere near the channel separation of what I am currently using,let alone distortion figures close to 4 Zeroes.I prefer to hear what the artist recorded, not an artificial rose tinted version of it. Still, if YOU prefer colouration , that's your perogative. I may be old, but I am not living in the middle of last century like some. ;D |

Anyway, I'm not asking you to listen to the music but to the noise level in the V2. Why should I when you already have discounted valves set long time ago. Let you have hifi music while we have "Live" music. ;D |

W.A.L.O.C.
Genuine High Fidelity is as close to Live music as you can get,
not what comes through crappy PA speakers at a gig..
Your definition of "Live Music" is how YOU would prefer it to sound.
Perhaps you like those big PA speakers that can be heard a Kilometre away ?
Go back to playing your vinyl collection.
Perhaps you can even find a working Black and White TV too ? ;D

;D You two are cracking me up!!! Chong - you are a naughty boy. Stop trying to wind Alex and Frans up!! What makes me laugh Alex, are the kids that download and listen 128 KBs mp3's and talk about the treble extension of the K701. (and the lack of bass) I saw a young guy listening to an Ipod with the Beyer DT1350 and he was telling me what high quality he was getting from his Atrac files at a really low bitrate. He put it all down to the mega headphones that he has. The noise thing on the V2 is surprisingly low to the ears. (Maybe because mine has been modded) I really don't hear any noise from it so anything more is theoretical for me. I'm currently comparing it to the Neco Mosfet and you know, I think the V2 is slightly better!! (Even though the Neco may be quieter I guess) I do miss black and white TV and The Hitchcock Half Hour. Gave me much more enjoyment than most of the crap on TV in high definition, stereo and colour nowadays. I used to go round changing tubes for people on their TV's when I was a kid and they paid me for it!! The funniest repair I did was to a TV that needed some soldering so I took it away on the back of my motorbike so I could do it at home out of site!!!! I absolutely LOVED our old Bakerlite radio. Jimmy Clitheroe, Sing Something Simple, and that guy that called out every Sunday afternnoon with 'Wakey Waaaaake Hey' and then the music went off. Not forgetting Hancock's half hour. Great days. |

Miguel too as he has been hearing and hearing at many meets until probably he hears babes calling out sweetly in those he heard as well. 
Maybe time for a valve change Ian, have you used it a lot since fitting them?
