I can see the same thing on my couple of Yugoslavian 6HM5 : a flash on one tube for only 1 seconds.   Are very nice and cheap tubes, but today is arrived a couple of Eico GE 6AV6 year 1958, and i'm in love...

I'm searching for a pair of 1958 GE 6AV6, that Gibosi have tested.   I have a pair of this tube, but built in the '70s, and i want to compare sound.   Will be ok FIVRE and Toshiba (Multivox), that have the same construction and design.   If someone now or in the future, can help me to find...

I will post a photo when will arrives.   I have a friend that told to me that sounds good.

  Bought a pair of this cheap tubes.   Seller write "with Philips/Mullard tube codes". I'm not sure, but seems have the same construction of GE Made in Great Britain by Mullard/Blackburn of Gibosi.   Can be the same ?  ...

How the tubes were made : i have found two old videos.   It's incredible what hard work is.   I have loved in special mode video number 2.   Enjoy   http://www.youtube.com/watch?v=hUSouYNvsMA   http://www.youtube.com/watch?v=fxXrfU36aY8

Today i've put my TS JTL6AH6WA on my LDi+   Strapped on 2-7 pins.   Sound in different mode from Others tube listened before, bass are present well, very deep soundstage, vocal a little bit warm and "cottoned ", but i feel hights not very clean and detailed. But i love this tube, after burn...

Ok, thank's again, now i know that my TS 6AH6WA 1964 are O-getters.   I think to be lucky

Someone can please explain to me  what is the meaning of O-getters or D-getters ?   What part of tube i must to look ? For example, i'm referring to my TS 6AH6WA, but i have no idea where and what to look.   Thank's

Today i want to talk about a pair of Jan GE 6AV6 5960, year 1973 ( cutted pin 5 and 6 ), EF92.   I have bought from NOS tube, for a price of 4 $ for a tube.   Sounds very well, as some other brands tryed before, detailed and transparent, voices forward and on your face, only a little harsh...

All clear, thank's.   Any kind of metal is ok ? i now that must be thin.... an electric cable with copper inside is ok ( isolated in the middle ) ?

Today are arrived 7 couples of tube, all in the same day   Voskhod 6J1P-EV (EF95 6F32 6AK7) Gold-Platinum grid ( matched ) year 1982 ----------(EF95)        One channel has a noise, i hope that finished burn in, noise will desappear.   Siemens 6AK5W (M8100, CV4010,5654) ------------  ...

Great Gibosi !!   I've recived today LME49990 opamp, must make more burn in, but i can say that first thing that i noted is  : refined, transparent, clean, treble are very detailed and come outside more ( and what quality !!) then previous opa.   Generally, for bass, medium, hight, is one...

I'm burning GE JG-5750 6BE6W, setting EF92, year 1958   Are fantastic tubes on my opinion, medium hights transparent, clear and very detailed, bass fast and not invasive on medium, female voices very nice, soundstage the best unltil now,  on corus is possible closing the eyes to collocate the...

Hi   i have placed on order for a pair of HI2050   I have Beyer DT880 edition 32 Ohm,  and i am curious to compare also with my 2 pairs of Superlux.

But now i become curious !!   i want to know for every brands the year of manufacture, there are links avalilable ?

 Svetlana are a very good surprise for me : balanced, open sound, clear, only a little harsh on hights, but i confide that after burn it will go away. It's a very small problem for my hears.   In origin, i don't give 1 cent, but now they have surprised me, i can put them in the hight part of...

Thank's   Now i'm listining on EF92, and sounds great

Received now a Soviet tube 6A2P  = 6BE6     I don't see it's name, may be Svetlana ?

I want to tell a great thank's to all members of this thread that let me know that exist other tubes different and better then stock, and to all that have helped me and other who did reviews.   I can tell that is true, any tube that i have leastened until now is without dubt better

    Received today micro cutting plier Pro-skit, cutted pin 5 and 6 on my Lorenz EBC91 (6AV6), it's very easy and safe.   Again this tube sound great (setting EF92 ) from the first moment, and i can tell : woww, and i smile!!   Medium/high transparent, clean, open and bright as the sun...

i know   really never i was thinking to cut pins on my Telefunken, sounds great.   Today i'm lucky, as i wrote before, and i'm learning some things that i don't know until that moment.   And another good news is that Pro-skit is shipped, so i can cut pins 5 and 6 on my 6AV6 and try...

First of the three settings on the manual ( to use WE408A ), for what kind and family of tubes can be used ?   Using with Telefunken EH900S don't work, it's normal ?

Thank's Michelap   i have made a change, and i have a big problem.   Tried Lorenz tubes with 408A configuration ( removed jumpers from j1 e j2, and k1/k2 switchies to the central pin and pin to the side marked 408A, ed immediately i see smoke coming out from electronic card side ).  ...

  Telefunken EH900S/5915 ( EF95 config ) sounds different from Tesla, more soundstage and more details, mids and highs are very clean and extended ,my surprise in that bass aren't too strong for my hears. More hight grade of trasparence . For my opinion sounds great without cutting pins...

I received today a pair of matched Tesla 6F32-6AK5   Now i'm burnin in        Received  Telefunken EH900S EH91 and Lorenz ITT 6AV6 EBC91 but my Pro'skit cutter is not until now dispached, so i must wait.   First impression about Tesla,that seems don't need burn in, unstrapped...
