I am currently auditioning a new breed of valve (tube) for the X-Can v2 / v3 and reckon they may be ok with the right power supply / suitable peep hole. Ladies and gentlemen allow me to introduce the Russian 6H6N....    6H6N next to a standard 6922..... a lot taller! First off.... sound quality is STUNNING! No doubt the absolute best I have heard in the X-Can v2 / v3.... the expansiveness of the soundstage, the bass extension, the dynamics.... you name it these valves have it. Secondly..... these tubes are relatively cheap. The downside? 1: They draw 750mA of heater current so will fry a stock MF wallwart within 1 hour. 2: They are a bit taller than the 6922 so will not fit inside a v2 enclosure (unless you provide peep holes) they will " just" make it into a v3 / v8 enclosure. I am currently experimenting with power supplies to see if these are a viable / safe insertion into the v2 / v3 / v8.... so far the results are: Stock 500mA lasted 1 hour before going into meltdown. Currently testing an "off the shelf" 1000mA transformer and she's VERY hot after 2 hours but still going strong...... Test three will, of course, be with one of my 2500mA Little Pinkies (I will report back in due course) Lessons learnt so far: Cool to use 6H6N with stock wallwart as long as you turn everything off after 59 minutes! Bastard good valves but a bugger to implement (if you run a v2) before you ask MIGUEL, the purple glow is quite simply a 5mm purple LED positioned underneath each valve base....... I drilled out a couple of holes under the valve bases and fitted LED's..... the pics are from my "open frame" v2 which is permanently exposed to the elements.... a trusty little "test bed". Anyways...... thought I'd share this with you all and will keep you updated  |

No wonder you ordered a 1,000M roll of cable !
Your PSU will be one of the few games in town capable of supplying those beasts. I suppose you also have a supply of mini 12V fans to keep the innards cooler ?

Wow, Alex must be going wild after all these tubes and more tubes threads. So Alex, are you rejoining us finally? LONG LIVE TUBES!Yeah, Amen after this .......................  Err, not Amen for the sound but Amen for the repercussion whenever tubes are mentioned here ....................  |

So this tube can replace all 12AX7?

Err, not Amen for the sound but Amen for the repercussion whenever tubes are mentioned here .................... XTRProf The bigger the tube, the better the sound of the breaking glass when it is dropped on concrete. Even Krisno seems to be slowly coming to the realisation that solid state can do much better ! I wonder how many inexperienced tweakers are going to damage their beloved valve gear, or it's power supply, either from overload or excessive internal heat , because they have plugged in valves with filament current demands, in the worst case scenario (heater current tolerances) almost TRIPLE that of the valve it was originally designed to take ? In any case, I am too busy finding errors in a schematic that has been around for several years, and all the so called tube experts haven't picked up on ! I wonder how many people have slavishly followed such reverse engineered, (AND drawn arse about to normal convention !) schematics, and either caused damage after modifications, or been disappointed with the results ? |

RobertKD Don't starved triodes make good "anode bend" detectors ? Might give some artificial "dither" to help camourflage their poor S/N ?  SandyK Rick Please don't get all serious with us, just a little fun giving some back to the Singapore Stallion. Alex |

Robert... this is my "open frame" X-Can v2 which sits on a block of wood.... its only purpose in life is to try out different valves and evaluate different caps..... it never gets put into an enclosure.
The "purple" you see are in fact purple LEDs that I have installed in the valve bases... purely cosmetic additions to this open frame v2....
Sandy..... the schematic on my website is not accurate but gives a general "overview" of the X-Can v2. I would certainly NEVER make the "actual" schematic available as it's not my property and I don't have permission from MF to do so.... much the same way as I wouldn't dream of uploading the schematics of any of Grahams designs.
The idea of the "almost there" schematic is for people like yourself who have a clue and can use it as a rough guide and put the pieces together for themselves..... not as a "here is what you require to build a v2 / painting by numbers" type thing.... if MF want to put their schematics online it's up to them, I certainly won't be doing it as it's not ethical.
The 6H6N sounds absolutely gorgeous in this circuit but, and it's a big but, she is a HUNGRY beast and will fry the stock wallwart in a matter of hours...... she also (obviously) runs a lot hotter than 6922 / E88CC and doesn't "fit" inside a v2 enclosure but good to know there's another "cheap" alternative to the 6922 / E88CC out there that performs so well (SQ)

These Russian 6N6P tubes (labelled 6H6N) are a bit of favourite with Lukasz Fikus, aka the Lampizator tube freak. Would like to have him and Alex as dinner party guests, hooweee Apparently they're very transparent which in part might have something to do with them providing low output impedance (~70 ohm). I bought a few last year to build a cathode follower stage for Leo's CS4397 el cheapo DAC which turned out to be quite good with opamp stage tweaks, and which the Lampizator site got me interested in. www.lampizator.eu/LAMPIZATOR/LAMPUCERA/CD%20DAC%20Lampucera%20lampizator.htmlAnother project parts bought for but not built ;D but hearing the good things said here .... cheers.. jeffc |

So this tube can replace all 12AX7? no at least not in all cases as the 6N6P has somewhat lower VA Max 120V vs about 300V so depending on circuit employed may OR may not work, then there would be various issues regarding operating point based on bias conditions and such,, as well as filament current as Alex pointed out. |

Anyways...... thought I'd share this with you all and will keep you updated Hi Mike Funny I should read this today I´ve actually been spending the whole day testing the 6H6N(6H6P) in my X Can V3. I ,ve been comparing it to E88CC Siemens, Sovtek 6922, Phillips 6922 and 6N1P. I`ve still not decided which one to use. I been using the 6H6N in my Copland CTA 301 mkII pre amp for a year now and there`s no doubt that in this amp, the difference between the Sovtek 6922 and the 6H6P is HUGE. It`s like getting a whole new amplifier ! I´m still testing as I write this at the moment Ì`m listening to the 6H1P tube and it sound very nice ! The problem with allt his tube testing is that the tubes has to play at least an hour or more, to get the right sound. The 6H6N can sound really awfull when they`re cold . It`s gonna take some time to finish testing. I`ll be back with my impressions of the different tubes in the X CAN V3 |

Maybe I have to remove the std tube sockets or  |

Hi guys,
Maybe you should try 6N1P instead of this one. 6N1P is much more closer to the E88CC than this one. It also though have a quite high heater current of 600 mA, which will impose some load on the supply. Therefore, it is not quite compatible. But it is smaller than this monster and still needs less current. It is a very good tube ...

I borrowed a pair from a friend to try them out.
They sound absolutely fabulous compared to the stock tubes.
But they dont fit in a v3 enclosure either.
Did anyone figure out how I can make them fit?(without drilling holes in the enclosure.)
They're about 6mm to high.
I returned them to my friend. But maybe if I can get them to fit and when I got a pinky I'll buy some of these myself.

Funky Angling is the only way....... tilt the sockets over at an angle (however you do this is up to you) you can get them to fit..... you want me to take a few pictures? |

In the meantime, here's the idea in a commercial unit, scroll down... www.6moons.com/audioreviews/melody5/sp9.htmlI seem to remember Musical Fidelity produced an amp of some sort, under the Michaelson Audio banner I think, that had horizontal valves too. |

OK... leave it with me I allmost don't dare to ask, but did you have a chance to post the pics of the v3 with these tubes? I haven't had time yet.... basically just BEND the sockets over and angle the valves so they don't interfere with the enclosure.... pretty crude but effective. |
